1. I can use a number line to graph and order real numbers. I can identify properties of and use operations with real numbers.

3. -3 -2 -1 0 1 2 3

4. PropertyAdditionMultiplication Commutativea + b = b + aab = ba Associative(a+b) + c = a + (b+c)(ab)c = a(bc) Identity a + 0 = a 0 + a = a a ∙ 1 = a 1 ∙ a = a Inverse a + (-a) = 0 Distributive a(b + c) = ab + ac

5. Identify the property:  (3 + 9) + 8 = 3 + (9 + 8) ◦ Associative property of addition  14 ∙ 1 = 14 ◦ Identity property of multiplication

7.  With a partner: ◦ Textbook pg. 7-8  19-22  29-30  33-38  44-54 even  55  When you are finished: ◦ Bring your work for me to check your understanding and to copy down your homework.
