1st Grade Math Worksheets
First grade is where addition and subtraction within 20 become facts rather than counting, where two-digit numbers turn into tens and ones, and where clocks and coins first appear. Each page below prints a fresh sheet for one of those skills.
Addition and Subtraction Within 20 is the everyday sheet for this year; the fact family, number bond and missing addend pages come at the same facts from the other side.

Frequently asked questions
What math should a 1st grader be able to do?
Add and subtract within 20, know the facts to 10 from memory, count and compare numbers to 120, understand tens and ones, and tell time to the hour and half hour.
How many problems should a first grader do at once?
Twenty to twenty-five is a normal single sitting. Most pages here can be switched to Half Page, which prints two shorter worksheets on one sheet.
How do I find out which facts my child still needs?
Print Addition and Subtraction Within 20 and watch while they work. Facts answered at once are known; facts worked out on fingers are the ones to practice. Then untick the numbers that are secure, so the next sheet spends its time on the rest.
Is there a timed test for the facts?
Yes. Mad Minute Math prints sixty single-digit addition and subtraction facts with a time and score box. Use it once the facts are mostly known, not while they are still being counted out.
Which pages teach that subtraction undoes addition?
Fact Family, Number Bonds and Missing Addend. Fact Family writes the four facts three numbers make, Number Bonds shows the same three as a whole and its two parts, and Missing Addend asks for the number that completes an addition, which is the matching subtraction. Each turns 9 - 5 from a new problem into a known fact.
