One maker for every step
- Within 10. The facts children learn first, a whole sheet at a time.
- Within 20. Sums that cross ten, like 8 + 5 and 7 + 6.
- Two digits, no regrouping. Add the ones, then the tens.
- Two digits with regrouping. Ten ones make a ten: carry it to the next column.
- Three digits. The same steps with hundreds.
Stacked or in a row
Stacked problems line the digits up in columns, the way children learn written addition with regrouping. Problems in a row (47 + 25 = ___) suit mental math and fact practice. Both come with an answer key.
More addition
For younger children, picture addition has groups of pictures to count before the number sentence. For taking away, the subtraction worksheets work the same way, with or without borrowing.
