Number bonds are taught in Primary 1 and then quietly dropped. This is one way to keep using them — for division, right through the primary years.
The method, on 98 ÷ 7:
• Split 98 into two parts, choosing a part that 7 divides cleanly: 70 and 28 • 70 ÷ 7 = 10 • 28 ÷ 7 = 4 • Add the answers: 10 + 4 = 14
And when it does not divide cleanly, on 80 ÷ 7:
• 80 splits into 70 and 10
• 70 ÷ 7 = 10
• 10 splits again into 7 and 3
• 7 ÷ 7 = 1, and the 3 is left over
• 10 + 1 = 11, remainder 3
The point is not that it is faster than long division. It is that the child chooses the split, which means they have to notice which numbers 7 goes into — and that noticing is the thing long division lets them skip.
