🧩 Mini Quiz – Quick Check

Try these after watching the video:

❓Question 1: 6 groups of 4 = ?

✅ Answer: 24

❓Question 2: 24 shared among 6 groups = ?

✅ Answer: 4 in each group

❓Question 3: Which operation fits “each”?

✅ Answer: Division

❓Question 4: Write 2 number sentences for 3 groups of 5

✅ Answer:

1. Multiplication: $3 \times 5 = 15$ 3×5=15
2. Division: $15 \div 3 = 5$ 15÷3=5 (or $15 \div 5 = 3$ 15÷5=3)

❓Question 5: Explain how × and ÷ are connected

✅ Answer: Multiplication (×) and division (÷) are inverse operations—multiplication combines equal groups to make a total, while division splits that total back into the original number of groups or group size.

Example from context: For 3 groups of 5 ( $3 \times 5 = 15$ 3×5=15), division reverses it: $15 \div 3 = 5$ 15÷3=5 (group size) or $15 \div 5 = 3$ 15÷5=3 (number of groups)
