β What is Division?
Division means sharing things equally or finding how many equal groups we can make.
- Sharing: 12 cookies shared by 3 friends β 12 Γ· 3 = 4 cookies each
- Grouping: 20 hockey cards in groups of 5 β 20 Γ· 5 = 4 groups
π¨βπ©βπ§βπ¦ Division Fact Families
Remember Fact Families from addition and subtraction? We have them for multiplication and division too!
Numbers: 6, 7, 42
6 Γ 7 = 42
7 Γ 6 = 42
42 Γ· 6 = 7
42 Γ· 7 = 6

π§ Helpful Strategies
1. Use Multiplication Facts
Think: βWhat times 6 equals 42?β β 7 Γ 6 = 42, so 42 Γ· 6 = 7
2. Equal Sharing
Draw circles (groups) and share dots equally.
3. Skip Counting Backwards
To find 56 Γ· 8, count backwards by 8s: 56, 48, 40, 32, 24, 16, 8, 0 β 7 groups
βοΈ Letβs Practice Together, My Dear Student!
Practice 1: Basic Division Facts
1. 24 Γ· 6 = 4
2. 35 Γ· 7 = 5
3. 42 Γ· 6 = 7
4. 63 Γ· 9 = 7
Practice 2: Missing Number
1. ___ Γ· 8 = 6 β 48
2. 54 Γ· ___ = 9 β 6
3. 72 Γ· 8 = ___ β 9
Practice 3: Word Problems (Canadian Style)
1. There are 48 students going on a field trip. They get into 6 equal buses. How many students in each bus?
48 Γ· 6 = 8 students
2. A hockey team scored 56 goals in 7 games. How many goals per game?
56 Γ· 7 = 8 goals per game
Challenge Question
Use the fact family of 9, 8, 72 to write all 4 facts.
9 Γ 8 = 72
8 Γ 9 = 72
72 Γ· 9 = 8
72 Γ· 8 = 9
Fantastic Job, My Dear Student! π
You are now getting really good at Division Facts! Keep practising with your multiplication facts β they are best friends!
I am so proud of how much you have learned in Operations. You are becoming a strong mathematician.
π You are smart. You are kind. You can do hard things.
When you are ready, tell me the next topic (Sharing and Grouping, Long Division Introduction, or anything else) and I will create another beautiful lesson just for you!
