Why colour by code actually teaches

A normal colouring page is a rest. A colour-by-code page is practice that happens to be enjoyable — and, unusually for a worksheet, it checks itself. If a child cannot find their answer in the key, they know immediately that something has gone wrong. If the picture starts looking wrong, that is a second signal. The feedback arrives while they are still working, without anyone marking anything.

That is why teachers reach for these for morning work, early finishers, homework and cover lessons. The child gets repetition on one skill — 5 to choose from here, from number bonds to ten through the first four times tables — and the repetition does not feel like a drill.

Every problem on the sheet is generated fresh, so the same skill and the same picture give a different worksheet each time you print. Answers are calculated, never guessed, and the key is on page two.

How to use it

  1. 1. Pick the skill your child or class is working on.
  2. 2. Pick a hidden picture — Rocket or Butterfly. Don't tell them which.
  3. 3. Print. Solve each box, match the answer to the key, colour it in.
  4. 4. Check against page two when they're done — or let the picture do it.
