What number bonds are for
A number bond is a whole split into two parts: 10 is 7 and 3, 6 and 4, 9 and 1. Children who know the bonds to 10 without counting have the building block for almost everything that follows: adding past ten, subtracting, making change, and later, mental arithmetic with bigger numbers.
Which sheet for which child
| Bonds to | Typical stage | What it builds |
|---|---|---|
| 5 | Reception / kindergarten | Seeing small numbers as parts and wholes |
| 10 | Year 1 / first grade | The core facts everything else leans on |
| 20 | Year 2 / second grade | Bridging through ten |
| 100 in tens | Year 2 and up | The same facts, scaled: 70 and 30 is 7 and 3 |
Getting more from a worksheet
- Short and often beats long and rare. Twelve questions a day for a week does more than sixty on a Sunday.
- Say it both ways. If 7 + ? = 10 is 3, then 10 − 7 is 3 too. Ask for the subtraction out loud after each answer.
- Use real objects first. Ten buttons, cover some, ask how many are hidden. The sheet is practice for something already understood, not the lesson itself.
- Print a fresh one. The same sheet twice tests memory of the page. A new set tests the facts.

Number Beasts: Bond Lab is an iPhone puzzle game built on the same idea. Numbers become projectiles: you launch the right part at a target to complete the bond, level by level.
