Instructions

Play through this interactive game to learn about Understand Multiplication Of Rational Numbers. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Multiply integers.
Identify sign of number resulting from a product of integers.
The rule for multiplying signed numbers is positive x negative = negative and negative x positive = negative and a negative x a negative = positive.
Use mathematical reasoning with signed numbers to prove rules for multiplying signed numbers.
Understand problems similar to ((-2) x (5 + (-3)) = (-2) x 5 + (-2) x (-3) then (-2) x (-3) = 6 since the number on the left is -4 and the first addend on the right is (-10).

Discussion Questions

Before the Game

What is the rule for multiplying signed numbers? What sign does the quotient have when the dividend is positive and the divisor is negative? How are the rules different for multiply and dividing integers compared to adding and subtracting them? What is the first step when using the distributive property? What are the order of operations?

After the Game

How do you know when the final result for the multiplication of integers is positive or negative? What strategy did you use to order the expressions when using the distributive property? If there was a time when you ordered the expressions incorrectly, what did you have to correct and why? When there were four dice rolled, how could you tell if the answer would be a positive or negative number? How can we use the distributive property to solve an algebraic equation?
