Curriculum Projects

Curriculum Project 1: What's New?

This project is designed to help you get a feeling for what some elementary mathematics textbooks look like, to familiarize you with "scope and sequence charts" and to get you thinking about where new material is introduced in the curriculum.

Background Reading

Before beginning the project you must read the article "How Much of the Content in Mathematics Textbooks is New?" by J.R. Flanders (to be distributed in class) and pages 497-499 of Van de Walle.

Assigned Texts

In order to prevent some of the competition for books and also to gave the class (and each group) see a variety of texts, I will assign you textbook series and grade levels to use.

The textbooks available in the curriculum center include the following

  1. Mathematics in Action, MacMillan, 1991. QA 107 M3835 1991.
  2. Mathematics: Exploring your world, Silver Burdett, 1992. QA 135.5 M3848 1992.
  3. Exploring Mathematics, Scott Foresman, 1996. QA 107 E97 1996.
  4. Math in My World, McGraw-Hill, 1998. QA 107 M258 1998.
  5. Math Central, Houghton-Mifflin, 1999. QA 107 H67 1999.

Use your card and the table below to determine your assigned textbook series. The letter indicates the series, the number indicates the grade level.

Report

Work in pairs for this project. Your partner is the person sitting at your table (same color and number card as you).

  1. Write a brief summary of Flanders' article. What was he main point and how did he try to demonstrate it?
  2. In the textbooks you are considering, what percentage is "new"? Be sure to explain how you arrived at these figures. Important notes:
You should prepare one type-written report for the two of you.

Curriculum Project 2: Problems, Problems, Problems

The gaol of this project is to help you see how different types of problems appear in elementary math texts. You will do this by looking finding problems of certain types from each of TWO different textbooks.

You may work in pairs for this project. This time you may choose your own partner. Use the same textbook for this project that one of you used for curriculum project 1 plus one assigned to one of you in the chart below. Use the same grade level in both textbook series.

  1. Investigations in Number, Data, and Space, TERC - Dale Seymour Publications, 1998. QA135.5 I58 1998.
  2. Math Trailblazers, University of Illinois -- Chicago and Kent/Hunt Publishing Co., 1998. QA 135.5 .K41 1998.
  3. Everyday Mathematics, Everyday Learning Corporation, 1992 and 1998. QA 135.5 .B472 1992, QA 135.5 .B473 1998.

Report

On pages 48-50, Van de Walle lists 9 types of problems that he claims "occur across most grade levels and content strands". In each of your two texts (one from the project 1 list and one from the project 2 list), find seven different problems that are examples of seven of these types. (That's 14 problems total.) For each problem Your report should be type-written (although you may supplement with hand-drawn pictures, etc, if needed). Be sure to include the information regarding which textbook(s) you used for the project.

Curriculum Project 3: Arithmetic Operations

You may work in pairs for this project. Whether you work in pairs or alone, you will need to look at TWO textbook series (and probably more than one book from each series). The goal is to find out when and how the arithmetic operations (addition, subtraction, multiplication and division) and algorithms are introduced in these two texts.

For the first, choose the series that one of you was assigned in project 1. For the second, use the chart below to determine which of the following texts to use:

  1. Investigations in Number, Data, and Space, TERC - Dale Seymour Publications, 1998. QA135.5 I58 1998.
  2. Math Trailblazers, University of Illinois -- Chicago and Kent/Hunt Publishing Co., 1998. QA 135.5 .K41 1998.
  3. Everyday Mathematics, Everyday Learning Corporation, 1992 and 1998. QA 135.5 .B472 1992, QA 135.5 .B473 1998.

Report

In each of the following, when asked to locate something, report the page, chapter, grade level and book (if the series has more than one book per grade level). Also estimate where approximately this topic falls in the school year (first quarter, second quarter, etc.) The scope and sequence chart will be useful for this, especially when there are several books involved.

Do this for each of the two textbook series you have been assigned. (Clearly label which is which.)

  1. Addition. Find out where in your series the addition algorithm for the sum of two 2-digit numbers is introduced. Do problems that involve regrouping occur along with those that do not? If not, locate where problems requiring regrouping first appear. What conceptual rationale is provided for the algorithm in each case?
  2. Multiplication. Where is the multiplication algorithm first introduced? (This will probably involve the product of a 1-digit number with a 2-digit number.) What conceptual rationale is given for the algorithm (repeated addition, array, something else, none at all)? Where does the product of two 2-digit numbers first appear? Does your textbook make use of an "intermediate algorithm" before moving to the "standard algorithm"? Support your answers with relevant examples and citations.
  3. Division.

Finally, give a quick comparison of the two textbook series. Do they do things similarly and at similar times or quite differently or at quite different times.


Curriculum Project 4: Division of Fractions

You may work in pairs for this project. Whether you work in pairs or alone, you will need to look at TWO textbook series. The goal is to find out when and how division of fractions is explained.

For the first textbook series, choose the series that one of you was assigned in project 1. For the second, use the charts from project 3 to determine which texts to use.

Report

In each textbook series, find the grade level where division of fractions is introduced for the first time. Where does this lesson occur? (Give the book(s), page, and chapter references as well the approximate location in the year -- first quarter, second quarter, etc. Note that for some texts this "unit" might be presented in several of the books at roughly the same time, be sure to explain this. Consult scope and sequence charts to help you locate things.) How is "invert-and-multiply" explained, or is it simply presented as a "rule"? Are any other algorithms for dividing fractions presented? In what order?
