1. FIND YOUR NEW SEAT!!! 1.Fill in Learning LogHW: 1) ATN p. 66-74 #10-13, 38-41 Complete answers: Show your Work! 2) Correct on our class website! 3) Inv 2 packet – check off tomorrow! 4) 30 mins of MathXLforSchool this week 2.On desk: Inv 3 packet (New), notebook, toolkit 3.Warm Up: Write the rules & give an example: Addition: Positive + Positive = Negative + Negative = Positive + Negative = Negative + Positive = Subtraction: Positive Negative Don’t Subtract, Add the Opposite! Then follow the Addition Rules:

2. 20 + 10 = 30 -20 + -10 = -30 -20 + 10 = -10 20 + -10 = 10 Don’t Subtract, Add the Opposite! Then follow the Addition Rules: Subtracting Integers 20 - 10 = 20 + -10 = 10 -20 – (-10)= -20 + 10 = -10

3. New packet: As a table group, complete the front page of Inv 3.2

4. As the number multiplied by 5 decreases by 1, the product decreases by 5 Look for patterns: How do the products change as the numbers multiplied by 5 decrease? packet

5. With each equation, there is one fewer group of 5.  5 less than 0 is -5  10 less than 0 is -10  15 less than 0 is -15

6. The product increases each time because you are accumulating fewer negatives (one less group of -4)

7. Each of the products is the opposite of the product of 4 and a negative number.

9. Positive Factors One Negative Factor Two Negative Factors

10. +6 - 6 Yes, multiplication is commutative! The order of the factors doesn’t matter. Positive x Positive = Positive Positive x Negative = Negative Negative x Positive = Negative

11. Negative x Negative = Positive Positive, 168 Negative, -240 Negative, -1 When there are zero or an even number of negative factors, the product is positive! When there is one or an odd number of negative factors, the product is negative!

12. Positive Negative Positive Negative Positive When there are zero or an even number of negative factors, the product is positive! When there is one or an odd number of negative factors, the product is negative!

13. Multiplying Integers - Rules Positive x Positive = Positive Positive x Negative = Negative Negative x Positive = Negative Negative x Negative = Positive
