Ryan's Great Big Book Of Integers

Chapter 1: Grade 7 Integer Review

What we remembered:

- integers can be represented on a number line

- "when subtracting something that isn't there, use a zero pair"

USING A ZERO PAIR:

3 - (-6) = 9

- 6 + 4 = (-10)

Chapter 2: Multiplying Integers

Chapter 3: Diving Integers

Question A: 6 ÷ 2 = ?

PARTITIVE DIVISION = spreading into parts or groups

This question says "How many parts or groups of (+2) are in 6?"

Question B: (-6) ÷ (-2) =

How many groups of (-2) are in (-6)?

Question C: (-6) ÷ 2 = ?

QUOTATIVE DIVISION = sharing

This question says "How do you share (-6) with 2 groups?"

Question D: 6 ÷ (-2) = ?

Using Multiplicative Inverse

6 ÷ (-2) = (-3)
