1st grade math worksheets
In first grade, children move from counting to real strategies: making ten, using doubles, and seeing subtraction as a missing addend (9 + ? = 14). The goal is fluent addition and subtraction within 10 and confident work within 20.
They also meet tens and ones, add two-digit numbers without regrouping, and tell time to the hour and half hour. Each worksheet below targets one of these skills and can be printed as often as you like.
What 1st grade students practice here
- Addition and subtraction facts within 20
- Tens and ones, two-digit sums without regrouping
- Missing addends
- Time to the hour and half hour
Every worksheet generates new problems each time, prints with an answer key on page 2, and can also be done online with instant checking. Teachers can send several of them as one online assignment, with no sign-up.
