Objective and Summary:
SWBAT understand rules for multiplying postive/negative integers by connecting to addition

You have four cards that say "-5" on them. Write an addition equation to find the sum.

CFS:
#1: Accurately interprets positive and negative signs
#2: Accurately writes equation

Represent the same four cards that say "-5" as multiplication. Write a multiplication equation.

Integer Cards--Mr. Kovalik removes two cards when playing the integer card game. The cards he removes are two, -3 point cards.
If he gets rid of these penalties, how will this affect his score?

Write a multiplication equation to represent the change to your test score.

CFS:
#1: Accurately interprets positive and negative signs
#2: Accurately writes equation

Calculate--What is the value of -4(-9)?

CFS:
#1: Accurately interprets positive and negative signs

MEDIUM Problems

Mix n Match--Match the multiplication expressions with their products.

(Drag the blue arrows on the left side up or down so that they match with the answer on the right side)

CFS:
#1: Accurately interprets positive and negative signs

SPICY--Try if you have time.

BE CREATIVE--Find multiple ways of getting a value of -18 through according to the criteria:

a) Use one positive and one negative number and multiplication.

b) Use only negative numbers and addition.

Derek wrote the following addition expression to represent the money he has spent on hats for Among Us:

-2+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)

Help him represent the total amount of money he has spent by writing an equivalent multiplication equation.

CFS:
#1: Accurately interprets positive and negative signs
#2: Accurately writes equation

Nice job! This is a shorter lesson, so please do the following: 

1) Practice more integer multiplication on IXL: (Search Codes: NB8, K7U, DQT)

2) Practice challenge skills like Algebra 1 or do more diagnostic practice to push yourself ahead!
