First Facts First
Everything in arithmetic grows out of the addition and subtraction facts a child learns in first grade. When 4 + 3 = 7 becomes instant, the mind is free to think about the bigger idea a problem is really asking. These worksheets keep the numbers small and the wins frequent, which is exactly what six- and seven-year-olds need to build confidence alongside skill.
How to Use These Worksheets with a First Grader
Keep sessions short and cheerful — five minutes of focused practice beats a long sitting every time. Start with the single-digit sheets, move to facts to 20 once those feel comfortable, and save the two-digit no-regrouping sheets for later in the year. Every worksheet downloads as a free PDF with a separate answer key, so checking work together takes seconds.
Hands Before Paper
First graders learn best when symbols connect to things they can touch. Pair these pages with counters, fingers, or a simple number line, and narrate the strategy out loud: "Start at 8, count on 3." Once a child can explain the strategy, the worksheet becomes practice instead of struggle — and fact fluency follows naturally.

Frequently Asked Questions
What math should a 1st grader know?
By the end of 1st grade, students should add and subtract within 20 (with fluency within 10), understand tens and ones, compare two-digit numbers, and add two-digit numbers without regrouping.
How many math problems should a 1st grader do per day?
Short, consistent practice is best. Five to ten minutes of daily practice — roughly 10 to 20 problems — is more effective than longer, infrequent sessions.
What order should 1st grade math skills be taught in?
Start with single-digit addition, then its matching subtraction facts, then extend to sums and differences within 20. Introduce tens-and-ones place value alongside, and finish the year with two-digit problems that do not require regrouping.
