Solution: Exercises 1 to 3
1 Basic fact family game
Exercise 1
In the multiplication fact family game, match these pairs: 3×4, 4×3, 2×6, 6×2. Which pairs belong to the same fact family?
Definition:

Fact Family Matching Game: An interactive game where players identify multiplication facts that use the same numbers and belong to the same fact family.

Method for fact family matching:
  1. Calculate the product of each multiplication fact
  2. Identify which facts have the same product
  3. Match facts that use the same three numbers
  4. Verify the commutative property relationships
Facts
3×4, 4×3, 2×6, 6×2
Products
12, 12, 12, 12
Match
3×4↔4×3, 2×6↔6×2
Fact Family Matching Game Board
3×4=12
4×3=12
Same Family!
2×6=12
6×2=12
Same Family!
Step 1: Calculate all products

3×4=12, 4×3=12, 2×6=12, 6×2=12

Step 2: Identify fact families

3×4 and 4×3 use numbers 3, 4, 12 → Same family

2×6 and 6×2 use numbers 2, 6, 12 → Same family

Step 3: Apply commutative property

3×4=4×3 and 2×6=6×2

Step 4: Match the pairs

Pair 1: 3×4 and 4×3 (fact family: 3, 4, 12)

Pair 2: 2×6 and 6×2 (fact family: 2, 6, 12)

Matched Pairs: (3×4, 4×3) and (2×6, 6×2)
Final answer:

3×4 matches with 4×3 (same fact family: 3, 4, 12)

2×6 matches with 6×2 (same fact family: 2, 6, 12)

Applied rules:

• Commutative Property: 3×4 = 4×3 and 2×6 = 6×2

• Fact Family Rule: Same 3 numbers create related facts

• Product Verification: All matched facts have the same product

2 Missing fact game
Exercise 2
In the missing fact game, if you see 7×8=56, what is the missing related fact in the same fact family?
Definition:

Missing Fact Game: A game where players identify the missing multiplication fact in a fact family when given one fact.

Given
7×8=56
Find
8×7=?
Complete
2 facts

7×8=56
?
56
7
8
?
Step 1: Identify the numbers

From 7×8=56, the three numbers are 7, 8, and 56.

Step 2: Apply the commutative property

Using commutative property: 7×8=56 means 8×7=56

Step 3: Verify the relationship

Check: 7×8=56 and 8×7=56

Step 4: Confirm the complete fact family

Both facts use the same numbers: 7, 8, 56

Missing Fact: 8×7=56
Final answer:

The missing related fact is 8×7=56

Applied rules:

• Commutative Property: Order doesn't matter in multiplication

• Fact Family Rule: 2 multiplication facts with same 3 numbers

• Missing Fact Strategy: Use commutative property to find the related fact

45
5×9=45
9×5=45
✓ Complete!
Step 1: Verify the fact family relationship

Check: 5 × 9 = 45, confirming these numbers form a fact family

Step 2: Write the first multiplication fact

5 × 9 = 45 (multiplying the two smaller numbers)

Step 3: Write the commutative fact

9 × 5 = 45 (applying commutative property)

Step 4: Count the total facts

Multiplication fact families always have exactly 2 facts

Complete Fact Family: 5×9=45, 9×5=45 (2 facts total)
Final answer:

Complete fact family: 5×9=45 and 9×5=45

You should have 2 facts in total

Applied rules:

• Fact Family Formation: One number equals product of other two

• Commutative Property: Order doesn't change product

• Fact Family Size: Multiplication fact families always have 2 facts

Solution: Exercises 4 to 5
4 True or false fact family game
Exercise 4
In the true or false game, is 6×7=42 and 7×6=43 a valid multiplication fact family? Answer true or false and explain.
Definition:

True or False Game: A game where players determine if given statements about fact families are mathematically correct.

Given
6×7=42 and 7×6=43
Check
42≠43
Result
False
True or False Fact Family Game
6×7=42
7×6=43
FALSE!
6
7
42
Step 1: Calculate the products

6×7=42 (correct)

7×6=42 (by commutative property, NOT 43)

Step 2: Check if both facts have the same product

42 ≠ 43, so these facts cannot be in the same family

Step 3: Apply the commutative property

If 6×7=42, then 7×6 must also equal 42

Step 4: Make the final determination

Since 7×6≠43, this is not a valid fact family

FALSE: 6×7=42 and 7×6=43 is NOT a valid fact family
Final answer:

FALSE

Explanation: 7×6=42, not 43. Both facts in a family must have the same product.

Applied rules:

• Commutative Property: If a×b=c, then b×a=c

• Fact Family Condition: All facts must have the same product

• Verification: Always check if mathematical relationships hold

5 Fact family sorting game
Exercise 5
In the sorting game, sort these facts into their correct fact families: 3×8, 4×6, 8×3, 6×4. How many different fact families do you have?
Definition:

Sorting Game: A game where players categorize multiplication facts into their correct fact families.

Facts
3×8, 4×6, 8×3, 6×4
Products
24, 24, 24, 24
Groups
2 fact families
Fact Family Sorting Game
3×8=24
8×3=24
Family 1
4×6=24
6×4=24
Family 2
Step 1: Calculate all products

3×8=24, 4×6=24, 8×3=24, 6×4=24

Step 2: Group facts by numbers used

Group 1: 3×8 and 8×3 (uses numbers 3, 8, 24)

Group 2: 4×6 and 6×4 (uses numbers 4, 6, 24)

Step 3: Apply commutative property

3×8=8×3 and 4×6=6×4

Step 4: Count the distinct fact families

Family 1: (3, 8, 24) and Family 2: (4, 6, 24)

Sorted Families: (3×8, 8×3) and (4×6, 6×4) → 2 different fact families
Final answer:

2 different fact families:

Family 1: 3×8=24 and 8×3=24 (numbers 3, 8, 24)

Family 2: 4×6=24 and 6×4=24 (numbers 4, 6, 24)

Applied rules:

• Fact Family Condition: Same 3 numbers create related facts

• Commutative Property: Order doesn't change product

• Sorting Strategy: Group by common sets of three numbers
