Teaching tip
"More on the floor, go next door": if the bottom ones digit is bigger, borrow a ten. This sheet is aligned with Common Core 2.NBT.B.5.
About this worksheet
Two-digit subtraction on graph paper where every problem needs regrouping, with a row on top for the new numbers.
What kids practice
Adding and subtracting two-digit numbers, like 47 + 25 and 63 - 28. The ones are added or subtracted first, then the tens. When the ones add up to 10 or more, 10 of them become 1 ten (carrying). When there aren't enough ones to take away, 1 ten becomes 10 ones (regrouping). Every problem in this topic uses two-digit numbers on both lines.
Watch for
- Writing 12 in the ones place instead of carrying the 1 ten.
- Subtracting the smaller digit from the bigger one in the ones (63 - 28 becomes 45).
- Forgetting to take 1 away from the tens after regrouping.
- Adding when the sign says subtract on the mixed page.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full adding and subtracting within 100 guide for 2nd grade.
