____________ PERIOD ____
(Use with the Lesson 8-7 Preview Activity on pages 450–451 in the Student
Edition.)
Materials:
algebra tiles, product mat
Model and Analyze
Use algebra tiles to find each product.
1. (x 2)(x 3) 2. (x 1)(x 3)
3. (x 1)(x 2) 4. (x 1)(2x 1)
5. (x 2)(2x 3) 6. (x 3)(2x 4)
7. You can also use the Distributive Property to find the
product of two binomials. The figure at the right shows
the model for (x 3)(x 4) separated into four parts.
Write a sentence or two explaining how this model
shows the use of the Distributive Property.
