You will learn to divide any number by 2, which means finding half.
🏪 Market Story
Emeka and his brother share everything equally. If they get 14 groundnuts, each gets half: 14 ÷ 2 = 7. If they get ₦50, each gets: ₦50 ÷ 2 = ₦25. Dividing by 2 is halving!
📝 Let's Learn
Dividing by 2 is the opposite of doubling. If you know your 2 times table, you know how to halve!
- 2 ÷ 2 = 1 (half of 2)
- 4 ÷ 2 = 2 (half of 4)
- 6 ÷ 2 = 3 (half of 6)
- 8 ÷ 2 = 4 (half of 8)
- 10 ÷ 2 = 5 (half of 10)
- 12 ÷ 2 = 6, 14 ÷ 2 = 7, 16 ÷ 2 = 8, 18 ÷ 2 = 9, 20 ÷ 2 = 10
Example 1: Half of 16 = 16 ÷ 2 = 8.
Example 2: Half of ₦100 = ₦100 ÷ 2 = ₦50.
Example 3: Half of 24 = 24 ÷ 2 = 12. (Think: 12 + 12 = 24.)

💡 Remember
Dividing by 2 is the same as finding half. It's the opposite of doubling. If you know that double 8 = 16, then half of 16 = 8!
