Skip counting by 10s worksheets
Every row counts by ten, and the sheet says so at the top. Five numbers in a run with one of the middle three missing, so a child counts on from the left and checks against the number on the right. Free printable sheets, with an answer key.

What's on this sheet
Counting by tens is where the tens digit becomes something a child can watch. 30, 40, 50 changes one digit and leaves the other alone, and saying that out loud is more use than any rule about it — it is place value arriving through the ear.
Why this sheet works
The runs start on a multiple of ten, which is what makes this skip counting rather than ten-more practice. 37, 47, 57 is the other exercise and it has its own sheet, because the question a child answers there is about the digit that changes rather than about the count.

- Work out the jump from numbers you can SEE — never from the gap, because the gap is what you are trying to find.
- 20 to 30 is up 10, and a counting sequence jumps the same amount every time.
- So the gap is 0 + 10 = 10.
