About this worksheet

Counting by tens helps children see 100 as ten equal groups instead of one very long string of single counts. The spoken pattern sounds simple, but children often say sixty after fifty and then lose the sequence, confuse sixty with sixteen, or leave out ninety before 100. On this page every item is a row of number cards that counts by tens, such as 30, 40, 50, 60, with one card left empty, and the child writes the missing number straight into the card.

Support sheets use the smaller numbers up to 70. Standard and challenge sheets go all the way to 100 and the empty card can be anywhere in the row. Say the row aloud, ten, twenty, thirty, and listen for the gap. Every number ends in zero, which is a good thing to point out.
