Dividing by 2: How Many Remains?

This activity is about dividing by 2.

Examples:

Work out the divisions below.

24 ÷ 2

We can split 24 into 20 + 4 and halve each number to get 10 + 2 = 12.

25 ÷ 2

We can split 25 into 20 + 5 and halve each number to get 10 + 2 rem 1 = 12 rem 1.

37 ÷ 2

We can split 37 into 30 + 7 and halve each number to get 15 + 3 rem 1 = 18 rem 1.

When we divide an even number by 2, there is no remainder.

When we divide an odd number by 2, there is always a remainder of 1.
