Title: Exploring Results of the NAEP: 1980s to the Present
Journal or Publisher: Mathematics Teaching in the Middle School
Volume, Issue, Pages: Vol. 14, No. 6, pgs 357-365
Reviewer: Sarah
Date of Review: February 15, 2009

This article reviewed the outcomes of the past three decades of the National Assessment of Educational Progress (NAEP). They focused mainly on the results of the 1973-2004 Long-Term Trend (LTT) Assessment in mathematics. Some of the items used on the test were released in 2006 and the authors go over the findings to see what our schools are lacking. They discovered that “results of the LTT assessment for middle-grades students show[ed] positive advancement”. However, more specifically they discovered areas that need to be addressed more in middle schools or that don’t need the emphasis as much as we thought.

The final part of the article spoke particularly to me because it spoke about how, although students have the ability to do the computations in word problems they aren’t as likely to score these points because of the more conceptual items involved in the problem. This leads me to believe that focusing on teaching through problem solving would be a good way to prepare the students for using their computation skills in real life examples.

This article on equity talks through an experience with a lesson taught by Kara Imm, one of the authors. She is trying to guide her students through as lesson on multiplying factions by using representation to real life situation. She speaks about how important the representation of mathematical ideas is to help students create a mindset of relevance and meaning in order for them to gain the necessary comprehension and skills. Although when a teacher creates their own representation of a problem it can sometimes be difficult to find an example that relates directly to the students. So because of this Imm suggests that instead of creating your own representations we allow the students to have a hand in creating the examples. This allows for a close to home representation of mathematics through a student’s idea for math in his or her own world. Another plus of letting students create their own representations is that then the teacher is able to use these ideas to furt

her gain insight on the background and culture of the students in the classroom. Through this article I was able to see how one would implement this strategy of student representation. She states 3 ways of creating equity in the classroom that really suck with me. She states that the 3 ways are; “(a) by helping students feel that they are a part of the culture of mathematics, (b) by creating a mathematics community, and (c) by holding students accountable for their mathematical growth.” I believe that through implementing these three steps a teacher can create more equality when creating representation example through realizing that students come from different backgrounds so varying the examples would help them get the mathematical ideas down through real life examples.

Cake is filled with sugar and cake a good real life example for thinking of algebra to get the correct amount of cake pieces for the party people. This article takes this idea of cutting a cake into pieces as an algebra problem and puts it to use connecting it to the standards and principles of middle school mathematics. Through this activity we can relate the cake example to the standards of algebra, problem solving, reasoning and proof, connections and representations. The article speaks on how each of these standards relates to the sharing of a cake problem through separate activities.

I believe that this is a good article because it clearly illustrates each of the planned lessons/activities. The most important part about each of the activities in the article is that it allows different ways to explore the problem of cutting the cake through the separate standards and principles. This is a good article to create a couple days focusing on this one problem of cutting the cake. I would use it to help teach students about how there are different ways to look at a problem and there are different conclusions. Plus it can become a great snack on the last day of the unit activity.

Date of Review: March 1, 2009

The goal is to make algebra more accessible to students and in order to do that we need to have enticing mathematics for students to gravitate towards in the classroom. The more traditional way of teacher algebra by tackling an equation without context, making a table, and graphing isn’t working. The authors suggest starting at concrete representations and then move to increasingly more abstract problems of the same concept. The most powerful of understandings occurs when students can come to recognize the connections between the learned representations. For the authors specific beginning problem to algebra they introduced a situation for students to find the different ways $10 could be used to buy two different priced candies. Students could then progress from being able to “build a strong base for representing real-world situations with tables and graphs, to introduce linear equations, and to bridge linear equations and systems of equations.”

This article gives a well-detailed approach to helping connect students with the algebra. I would use this grouping of activities to create a foundation for algebra for my pre-algebra students. The lesson walks you through the different ways to see the problem and also creates options for you to take the more experienced students further into their learning of the subject and modifications for younger and special needs students. This article has a good set up so that you may easily differentiate the different intensities and learning style of several different groups of students within he same classroom.

Title: Using Origami to Promote Geometric Communication
Journal or Publisher: Mathematics Teaching in the Middle School
Volume, Issue, Pages: Vol. 9, No. 4 222-229
Reviewer: Sarah
Date of Review: March 3, 2009

This article uses origami to teach students geometry, developing their knowledge of spatial sense, properties of shapes, congruence, similarity and symmetry. It also shows students about the multicultural connections in math and deals mostly with the concept of communication in the classroom. It is important for all students to communicate their own mathematical thinking to their peers and teachers. Using words to express mathematical ideas and problems can be difficult for students who have never been asked to do so before. It is imperative to remember that as teacher we need to facilitate this discussion within the math classroom. Research has shown that when students know how to express themselves mathematically it increases their understanding of the concepts and ideas. “Mathematics becomes personal through oral communication”(223).

The lesson described in this article is planned to take two 50-minute periods. As an overview the lesson uses “cooperative group learning, peer teaching, journal writing, and a hands-on approach to teach geometric concepts”(224). I am especially attracted to the part of the lesson when they are actually doing the folding of the origami. Instead of just handing out instruction for how to fold the paper a question guide accompanies the students and asks questions after each fold. Each question brings the origami lesson to a new level of learning through communication between the students at the group tables. It forces the students to actually think about how the paper is being folded. The questions relate back to the main concepts of geometry; shape, area, and fractions of shapes. The second part of the lesson has the students teach their partners about how to make the model that they had perfected. Once again, there are question that follow after each has taught their neighbor, forcing the students to think and explain how they communicated the origami.

I especially enjoyed this article. It is full of ideas to help generate communication of mathematics within the classroom. By allowing students to become the teachers it lets them dive deeper into their schoolwork. All the activities in the article meet the Geometry Standard of NCTM. The article also has further extensions that a teacher could pursue to help the students explore the origami even further. If I was teaching a geometry lesson I would want to use this plan to help my students understand how to communicate the mathematics that they were doing.

Date of Review: March 8, 2009

The article use of three scenarios shows us the idea of relative size of fractions, fraction computations and proportional reasoning illustrating some of the standards of middle school math. The authors describe classroom experiences with the previous problems to understand rational numbers. They found that when students are asked to “determine the larger of two fractions or two decimals, they often do not have a sense of the size of that value when it is related to 0, ½, and 1”(282).

They introduced the game of “red light, green light” to help describe the fractions from the distance to the start and finish line. They found that some students would rely on their understanding of decimals and convert the fractions in order to find the position on the number line. Some students used rulers to find the fractions. The article talks about the different ways students used to find the fractions of the distance of the players. They found that some students used “flexi! bility with numbers include[ing] (1) working flexibly within a form (i.e., among fractions only); (2) moving among fractions, decimals, and percents; and (3) knowing which form is most useful, given the problem at hand”(284). Further into the lesson we develop which of these forms is most useful according to different situations. Additional problems were given to the students to help them see these differences. They need a lot of experiences to guide them to develop their understanding of problem solving and examples were given to guide them to different forms.

Lastly the article talked about how it incorporates the meanings and use of mathematical operations and proportionality into the context. By focusing on the understanding of the operations students can apply their knowledge to help create algorithms for shifting from whole numbers to fractions. By allowing the students to experiment with their own algorithms it allows them to make sense in their own way about the rule to “multiply by the reciprocal” for fractions. This article gave a good overview of some ideas to help middle school students use fractions in context to help intrigue the students and engage them in the learning that is taking place in the classroom. It is important to start students to think with a rational mind in order to start a successful path toward algebra.

Title: Means and MADs
Journal or Publisher: Mathematics Teaching in the Middle School
Volume, Issue, Pages: Vol. 4, No. 6 ,pg 398-403
Reviewer: Sarah
Date of Review: March 10, 2009

The article builds an activity that can be used to help students understand the idea of variation from the mean. By developing concepts like distribution of data, variation in data and the use of MAD as a measurement of variation in the data students are introduced into the main concepts of statistics. The activity is surrounded around a problem of how many people are in the students’ families. By using sticky notes the students created a line plot displaying the data of family size for 9 families that had a mean of 5. They students had to rely on their knowledge of how to calculate the mean in order to create a distribution on the number line that corresponded to a mean of 5. After each group of students had created a different number line with their sticky notes they were asked to compare the different plots all with mean 5. It became prevalent that although knowing the mean can give us information about the total population it doesn’t provide us with enough information to talk about the distribution of the data.

Taking the activity to its main goal the teacher then helped walk the students through describing the different distributions in each of the plots that had been made, finally coming to the definition of deviation from the mean as value-mean. Recognizing that there is a difference in the deviation of each of the plots is important to understand that each plot illustrates a different idea. The second part of the lesson demonstrates for the students the definition of MAD (mean absolute deviation) and how to implicate it in each of the example data sets. Furthermore the teacher not only develops and understanding of how to find the MAD but also how to comprehend it within the context.

I find this article to be a good framework for a lesson surrounding statistics and mean however I’m still a little bit confused about the idea of MAD. I had never heard that term before and am interested in if this is still used today. The overall approach to an introduction to deviation works well within an engaged classroom and would be appropriate to use to help develop students’ further understanding of how to read and analyze data.

Reviewer: Sarah
Date of Review: March 15, 2009

This article uses mathematics involved in the NCAA basketball tournament to begin or review a unit on probability and statistics. The author suggests doing the unit before or after spring break in order to help motivate the students during that difficult time when spirits and minds are outside of the classroom and focused on spring.

The article begins by talking about the tournament terminology for people like myself who know nothing about the NCAA tournament. The tournament is called “March Madness” and the first round has 64 teams with 32 winners, then leading into the “Sweet Sixteen”, then 8, then 4, then the final two resulting in a winner. Some of the math used to figure out the strength of schedule is to use the rating percentage index (RPI). The committee uses the RPI to figure out what teams should be placed where in the tournament. The article talks about the history of the seeds and how to compute the RPI for a team.

The second part of the lesson talks about probability and figuring out the possibilities that certain seeds will win certain games. Then leads into the idea of expected value as an event of average for figuring out the long run events and multiplication principle. The author begins each of the sections with examples of the ideas with connections to easier problems before introducing the harder basketball connections. The article also includes a great exercise to review the material learned. It also recommends an additional project that can create some competition between the students giving them a chance to try and use the math to pick the final four teams for the men’s and women’s tournaments. Over all a very worthwhile article especially if there are a lot of students who are real big fans of basketball and the tournament.

Date of Review: March 17, 2009

The article helps teachers make algebra interesting for students. There are many students believe that they can’t do algebra because they believe it to be a lot of “symbol manipulations” and solving complicated equations. The author describes several activities that he has used in the past to get students involved in their learning of algebra. He uses “puzzles and patterns that lead to algebraic generalizations” to help students see the ideas and create their own problems.

The first activity is called the constant-sum grid. This activity uses a 4-by-4 grid filled with numbers. Then by following 9 steps and adding up the sum of the circled numbers it will always be 45. The teacher will guide the students through the activity and encourage them to look for patterns and help figure out why they always have the same sum even though different sets of numbers are circled. There are good follow up questions that allow students to explore the idea further to develop a better understanding of the algebraic pattern.

The second activity is an exploration of the Fibonacci sequence. By creating their own Fibonacci sequence students figure the pattern through exploration and some algebraic guidance. The third is called predict your age uses an algorithm to set up an answer to a person’s age and number of people in their family. It seems like mind reading until students have the ability to see the algebraic steps that were taken to get to the answer. The final activity is called target 21. This games also involves 2 students choosing a number 1, 2, or 3 to add on to the previous total switching turns and starting at 0, the first student to reach to 21 wins. The students will look backwards to figure out how to always win the game by finding safe numbers.

All this activities help students come to understand the importance of algebra when it is used to generalize situations by creating a game/activity students are more likely to be engaged and motivated to find solutions. These can be starting points to introduce students to formulate a general arithmetic sequence. The activities are described in good detail and could be used in a classroom setting. They are interesting, help students develop an algebraic way of thinking and let students create new problems and puzzles of their own. Over all this would be an excellent article to read and implement if introducing students to algebra through games and activities.

Date of Review: April 1, 2009

With around 5 million students considered ELLs it is important to further education for teachers about how to best reach these students. The four principles that are used to develop language acquisition are (1) comprehensible input, (2) contextualized instruction, (3) a low-anxiety learning environment, and (4) meaningful engagement in learning activities. The article walks through these four principles and offers suggestions to how they can be used within the mathematics classroom. There is a very complete table, which summarizes these principles and adds specific strategies that can be used to help teach the principle.

The second part of the article walks through investigating the perimeter and area of objects through problem-solving techniques. By participating in the development of the formulas students will gather a better understanding for the definition and use of the formula. Through investigations the article walks through engaging activities that will further a students understanding of area and perimeter. Through these investigations they are required to use the principles above to explain the activities. The careful exploration of the shapes is enhanced through the language proficiency that is being acquired through the problem-solving activities.

I would highly recommend reading this article mainly for the table that organizes the language acquisition principles and strategies. If one is ever working in a classroom with ELL students it is important to remember that there are many useful recourses out there that can be of much use when trying to create lesson plans that are helpful to create language proficiency while still teaching mathematics.

Date of Review: April 5, 2009

The main point to always keep in mind is that technology does not replace the need to teach basic understandings and skills. As teachers we need to learn how to use the technology as an additional manipulative to help the students understand in an supplementary way. The article walks through the different content stands of mathematics; data analysis and probability, algebra, number and operations, geometry, and measurement. Each sections speaks on a separate content stands giving specific activities that can be used with technology along with the program (particular technology) that can help do this.

The five examples implement the use of the calculator, spreadsheets, geometric software, and a CBR that tracks movement. Each of the examples would prove to be much more time consuming and difficult with the absence of the necessary technological tools. Although the sections speaking on the stands are very short I believe this is a good jump-start towards implementing technology in the classroom across all the stands presented as examples.

Date of Review: April 19, 2009

Tom Santulli believes that “providing a real-world context and requiring multiple representations will promote students’ understanding of problems.” It is important to have many levels of representations to allow for students to understand how to use the tools properly. Santulli believes that it is critical for middle school math to teach students the necessary representations in order to succeed in high-level high school mathematics. It is key to help students recognize that problems can be represented in several forms as to help their overall comprehension of the problem. It is the job of the teacher to help take the students from the elementary understanding of representation from grade school into a more advanced comprehension that will allow for them to be successful problem solvers.

The article walks us through 4 problems using the themes of car rentals, boxes, movie tickets and dog grooming. The 4 problems show different representations for the problem. Through a successful use of all 3 representations for problem 1, the dog-grooming problem, will make the high mathematics more accessible to the students. By making a table to represent the problem then move on to a functional equation then a graphical representation allows for easy access of the mathematics for the students. The next problems trail as more challenging follow-ups to the idea of representations and problem solving. Each detailed enough to implement within the classroom as a successful problem solving representation lesson. By helping students understand multiple representations we are allowing for them to reach higher levels in mathematical understanding.

“A standards-based approach in mathematics involves using story problems to allow students to investigate a solution. This approach emphasizes an understanding of concepts and processes and assumes mastery of basic computation skills.” The new NCTM goals are to help students and teachers change their thinking of mathematics. The article speaks on Elizabeth Brucker’s journey towards a belief in standard-based teaching. Brucker struggled in mathematics as an elementary student and when she began her career as an elementary school teacher she carried that discomfort with her. She would avoid the word problems in the books as she saw them as extremely challenging. She realized that these problems were the best parts of the lesson by teaching students to think. The rest of the article she talks about her journey to becoming a better math teacher as her love for math grew. She concludes saying that it is important for teachers to have training to be able to teach standard-based mathematics correctly and effectively.

Volume, Issue, Pages:
Reviewer: Sarah
Date of Review: April 19, 2009

“School algebra has to do with the understanding of “letters” and their operations.” This school algebra is so different from the mathematics of algebra taught in college. Considering the following equation of two numbers equaling a third and their use of variables:

1. A=LW

2. 40=5x

3. sinx=cosx X tanx

4. 1=nX(1/n)

5. y=kx

Each of these has a specific definition within algebra (1) a formula, (2) an equation to solve, (3) an identity, (4) a property, and (5) an equation of a function. Today the idea of a variable is the “symbol for an element of a replacement set”.

The two fundamental issues in algebra are the requirement to be able to do various manipulative skills by hand and the question of the role of functions and the timing of their introduction. There are four conceptions presented in this article; algebra as generalized arithmetic (pattern generalizers), as a study of procedures solving certain kinds of problems (unknowns and constants), as the study of relationships among quantities(arguments, parameters) and as the study of structures(arbitrary marks on paper).

Date of Review: April 19, 2009

Examples of cultural geometric art are used to teach a lesson in symmetry and geometric patterns. This article goes through several lessons designed to help students learn about two-dimensional geometry by creating their own ceramic tiles. Through the exploration of lines, angles, circles, triangles, quadrilaterals, and regular and nonregular polygons the students gather properties in order to create their own tile. As they are going through the lessons they “develop more precise descriptions and classifications, thus increasing their ability to create and critique inductive and deductive arguments concerning geometric ideas and relationships.”

Lesson 1 explores regular polygons to start scaffolding up towards the larger concepts. The second lesson delves into the concepts of construction of a regular hexagon. Lesson 3 goes into the examinations of the art of cultures and then in lesson 4 has students recreate the designs from the previous lesson. Each lesson builds on the previous guiding the students towards creating a beautiful geometric design for their tiles.

Reviewer: Sarah
Date of Review: April 21, 2009

This research project analyses the problem solving skills based on reading comprehension. There were 98 sixth and seventh graders who participated by having their problem-solving behaviors classified into five categories. They found that to succeed in solving word problems students must be able to transform elements of the word problem into a whole conceptual idea.

The “findings of this study suggest several potentially crucial components [by] translating the text of a word problem, constructing an accurate mental model, and solving mathematics word problems”(208).

Some important characteristics found in the research included;

-student recorded the information of the problem

-student used in context with units and associations and to support conclusion

-the more successful students showed evidence that they translated and organized the information by rewriting

There are five main categories;

Direct Translation Approach (DTA)-not proficient-lack of competence and have difficulty reading the problem, coming to an understanding of the problem, deciding on a solution, performing calculations, students also are hesitant in moving towards a solution. They reread the problem and some calculation may not even be related to the problem.

DTA-proficient- Students can automatically and efficiently translate elements of the problem into a mathematical computation with only one reading.

DTA-limited context-they can translate the elements of the problem to arithmetic computation but with limited context.

Meaning-Based Approach (MBA)-full context-Students read and reread the sentences of the problem and record the information in the correct context and use this to support calculations. The final answer is given in a complete sentence.

MBA-justification- is similar to the previous classification but in addition student have evidence/justification for each step.

There are many great tips for teachers to use for teaching problem solving. Each article has several different sections. They begin with a Strategy Spotlight-the main problem, Classroom Climate (talks about different techniques for working in the classroom), Problem Corner, Developing Problem-solving Skills, tips from readers, try this, background ideas, take a look, and give it a try. Each of the sections helps work through the problem-solving articles through their own tips and techniques. There are a couple of techniques that I felt were good and should be mentioned in my review.

The four top method-

1. Read the problem (important information, visualize the situation, restate the problem)

2. Diagram or represent the problem (is the data correct, what conclusions can you draw)

3. Set up the calculations and compute (computations correct, all important data included and organized).

4. Write the answer (does the answer make sense, can you check it).

To help motivate students and their interest in the problem solving. Personalize the problem to meet the students’ interests. Use some students’ problems by having them write their own. Use interesting data for example world records or polls.

These articles work well to help teachers work through different ways to work through problem solving in their classroom. It is organized well and would be easy to implement in the classroom.

Date of Review: May 3, 2009

This workshop at the MCTM conference discussed research that had been done to help explain algebraic thinking in elementary students and how that translates into middle school algebraic thinking. The speaker helped us see that we are disconnected from the equations as we solve for the “correct” answer and she believes that as teachers we need to reconnect students to their own thinking (meta-cognition). Sue Wygant spoke on how we need to focus on three main factors when teaching algebra; the underlying ideas, student work, and where the learning is going next.

In addition she defined mathematical proficiency by 5 separate strands; conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. These strands all need to be covered in depth in order to ensure that students will achieve the algebraic thinking necessary. As a conclusion she stated that for kids to learn mathematics as teachers we need to engage student’s preconceptions, acknowledge that understanding requires factual knowledge and conceptual procedures, and a meta-cognition approach enables students to self motivate.

Included in the introduction to each cluster there is a set of objectives directly relating to the cluster. The introduction then goes through each activity with the materials needed and teaching notes on each. Following the introduction are the activity work sheets that are helping students reach the objectives previously stated in the cluster.

The Navigation series book go through the NCTM standards and organizes them into activities to follow these standards. Once again I looked at the ideas focused on transformations and symmetry in geometry. In the introduction it speaks on the importance of these specific mathematical ideas and through the individual standards indicated by NCTM. The second part of the introduction to the chapter talks about “what might students already know about these ideas?”

After the introduction to the topic of the chapter the activities are presented. Each activity is organized in the following manner. First with the goals directly relating to the standards, then a list of the materials needed for the activity, the main instruction of the activity and discussion after the activity. I believe that these are important books to acquire throughout teaching to help develop a rich collection of activities that can be used to supplement the curriculum.
