Part B:  Complete quadrant 2 of the table.

What relationships or patterns do you notice between the products (values) in quadrant two and the products (values) in quadrant 1?

What relationships or patterns do you notice between the products (values) in quadrant two and the products (values) in quadrant four?

Use what you know about the products (values) in quadrant one, two, and four to describe what quadrant three will look like when its products (values) are entered.

Part C:  Complete the quadrant 3 of the table.

Refer to the completed table to help you answer the following questions:

f.   Is it possible to know the sign of a product of two integers just by knowing in which quadrant each integer is located?  Explain.

g. Which quadrants contain which values?  Describe an integer game scenario represented in each quadrant. 1 2 3 4 5

We have used the Integer Game to explain that adding a number multiple times has the same effect as removing the opposite value the same number of times.  What is (­1)    (­1) ?x

Why are 1 and ­1 called additive inverses? Write an equation that shows this property.
