- 1. AIM: Multiplying and Dividing Integers Do Now Evaluate the following expression. a.) -3 - 5 + (-4) - (-2) 1
- 2. Multiplication Repeated Addition Sum 3 (-5) -5 + ( -5 ) + ( -5) - 15 2
- 3. Multiplication Repeated Addition Sum 3 (-5) -5 + ( -5 ) + ( -5) - 15 5 (-4) 2 (-8) 4 (-10) 3
- 4. Multiplication Repeated Addition Sum 3 (-5) -5 + ( -5 ) + ( -5) - 15 2. What do you notice about the signs of the sums? 3. What do these examples suggest about the product of a positive and a negative integer? 4
- 5. Think-Pair-Share Activity: Multiply 4.) -5 2 5.) -4 7 6.) 9 (-8) 5
- 6. Use the pattern to find each product. 2(-5) = 1(-5) = 0(-5) = -1(-5) = -2(-5) = 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 What conclusion about a negative number multiplied by a negative number based on this pattern? 6
