Counting to twenty

Twenty is the first big counting goal, and rows of five match the fingers on one hand: each row is a handful, and two rows make ten. The squares are 18 mm across, large enough to point at, colour in or cover with a counter.

Set Numbers shown to Some missing for a fill-in-the-gaps sheet, or to Blank for an empty chart the children number themselves. Raise the last number to 50 or 100 when they are ready for more.

Every sheet here is free, adjustable and prints at exact scale.

Questions

Why rows of five?

Five is one hand, so a row of five is easy to count and two rows make ten. Set Numbers per row to 10 for two rows of ten instead.

Can I make a missing numbers version?

Yes. Set Numbers shown to Some missing and choose how many to blank out; change the version number for a different set of gaps.

What comes after the 1–20 chart?

The 1–50 number chart, then the full hundreds chart from 1 to 100.
