1. AIM: HOW CAN WE MULTIPLY AND DIVIDE INTEGERS? Do Now: Evaluate each of the following problems (-5) + (-2) (10) – (-7) (-12) – (-6) (1) + (-8)

2. RULES FOR MULTIPLYING INTEGERS  The product of two integers with the same sign is always positive. Ex: -5(-8) = 40  The product of two integers with different signs is always negative. Ex: -6(3) = -12

3. RULES FOR DIVIDING INTEGERS  The quotient of two integers with the same sign is always positive. Ex: (-12) / (-3) = 4  The quotient of two integers with different signs is always negative. Ex: (81) / (-9) = -9

4. FACE RULE FOR MULTIPLYING AND DIVIDING INTEGERS + - + - + - + - -

5. HERE’S A SONG TO HELP US REMEMBER HOW TO MULTIPLY AND DIVIDE INTEGERS Multiplying / Dividing Integers May be sung to the tune of “Are You Sleeping?” Multiplying Integers Is easy as pie Like signs is positive Unlike signs is negative Easy as pie (*Repeat except change first to lines to Dividing Integers)

6. LET’S TRY SOME EXAMPLES TOGETHER  -3 (-12)  7 (-9)  -5 (11)  -72 / 9  -48 / -4  39 / -3
