Adding within 5 worksheets

Every sum on this page stays at five or under, which is the whole point: five is the first number a child holds in their head without counting, and the sums that fit inside it are the ones worth knowing by heart.

What's on this sheet

Five is where fluency starts. A kindergartener who has to count out 3 + 2 on their fingers every time has not finished with it; one who says “five” is ready for 3 + 4. So this sheet deliberately stops at five rather than ten, and the pictures are there to be counted at first and then not needed.

Why this sheet works

The groups are small enough to see without counting. Three dots and two dots read as a shape rather than as a queue, which is the thing that turns counting into knowing — and it is why the pictures are grouped rather than printed in one long line.

How this one works

1 + 4

+••••
hold:4count on:1

1 + 4 =5
  1. Both groups are there to be counted, and counting all of them from 1 is what most people do first. There is a shorter way that also works when the numbers get too big to draw.
  2. Start from the BIGGER one — 4 — and count the other 1 on from there. 1 + 4 and 4 + 1 land in the same place, so you are allowed to pick.
  3. 4, then 5 — 5.
