2nd Grade Math Worksheets
Second grade math worksheets practice two- and three-digit addition and subtraction with regrouping, place value up to 1,000, and telling time to five-minute intervals. These pages give seven- and eight-year-olds repeated practice with carrying and borrowing, which is usually the biggest new challenge of the year.

What is regrouping in math?
Regrouping, also called carrying or borrowing, is exchanging 10 ones for 1 ten (or the reverse) when adding or subtracting multi-digit numbers.
How do I know if my 2nd grader needs more regrouping practice?
If they frequently misalign columns or forget to carry or borrow, a few extra worksheets focused only on regrouping will help.
What place value should a 2nd grader know?
Second graders should understand hundreds, tens, and ones and be able to read and write numbers up to 1,000.
Do 2nd graders start learning multiplication?
Many 2nd grade classrooms introduce multiplication informally through repeated addition and arrays, ahead of formal fact memorization in 3rd grade.
How is telling time to five minutes different from the half hour?
It requires counting by fives around the whole clock face instead of just recognizing the hour and half-hour positions, so it takes more repetition.
