Objective:

    To show a variety of algebraic expressions factored using geometric representations.

Materials:

    One set of algebra tiles which includes:

      3 - "a" unit by "a" unit squares
      4 - "a" unit by "b" unit rectangles
      3 - "b" unit by "b" unit squares

Procedure 1:

    Ask the students to form a square or rectangle using the algebra tiles that shows

    One possibility would look like this:

Questions To Ask:

  1. What figure does this make? A square or a rectangle? Why?

  2. What is the length of each side?

  3. If you rearrange the squares and rectangles making up the larger square, what do you have?

      Answer:
