Objective and Summary:

SWBAT understand rules for multiplying postive/negative integers by connecting to addition

Pitanje 1
1.

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

Pitanje 2
2.

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

Pitanje 3
3.

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?

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!
