Grade 1 math worksheets
First graders work with numbers within 20 and two-digit numbers: adding and subtracting small amounts, reading numbers as tens and ones, comparing lengths, telling time on the hour and half hour, and naming basic shapes.

How Grade 1 builds
Addition and subtraction begin within 10 and stretch to 20 before missing-number equations appear. Place value moves from counting tens and ones to expanded form. Picture-based sharing and equal groups preview multiplication and division without any symbols.
Using the worksheets
Warm-up
Open a lesson with a within-10 addition or subtraction sheet at Easy; five minutes is plenty.
Homework
Send home a single Standard sheet with its answer key so a parent can check the work together with the child.
Review
After a unit on time or shapes, print the matching topic sheet and let children work through it independently.
Small-group support
Drop to Easy and the earlier skill in a topic (within 10 before within 20) for children still counting on their fingers.
Every worksheet is freshly generated with a separate answer key. Related standards appear on each topic and skill page as Common Core–informed practice, not a claim of official alignment. Nearby: Grade 2.
