First grade math worksheets: a sample week
A little practice every day works better than one long session. Here is a simple plan using the 1st grade math worksheets on this page:
- Monday: an addition within 20 page, solved with a number line or ten frames.
- Tuesday: tens and ones: build each number with blocks or draw sticks and dots before writing it.
- Wednesday: subtraction within 20, then two quick story problems read aloud together.
- Thursday: counting to 120 on a 120 chart, filling in the missing numbers.
- Friday: a telling time or shapes page, plus a five-minute fact game.
Ten to fifteen minutes a day is plenty for most six- and seven-year-olds.
Helping every child with 1st grade math worksheets
If a page feels hard, go back to objects: counters, coins, blocks or fingers make numbers real before they move onto paper. Use the easier version of the same topic and let your child succeed a few times before stepping up. If a page is too easy, press Customize for bigger numbers, mix two topics, or move on to the matching 2nd grade skill. Strong number sense, the feel for how numbers relate to each other, matters more than speed at this age, so praise good thinking as much as right answers.
Tips for using 1st grade math worksheets at home
- Practice facts a little every day. Five minutes of daily practice beats one long session a week.
- Use a hundreds chart or 120 chart to show 10 more and 10 less as moving down or up a row.
- Ask "how did you figure that out?" Explaining a strategy builds number sense faster than memorizing.
- Mix pages: a fact drill, then a picture puzzle or riddle keeps practice fun.

How many addition facts are there in 1st grade?
Standard 1.OA.C.6 asks first graders to add and subtract fluently within 10. We counted what that means for a child, and what happens when you go to 20:
| First grade fact set | Ordered facts | Different facts |
|---|---|---|
| Addition within 10 | 66 | 36 |
| Addition within 20 (addends up to 10) | 121 | 66 |
There are 36 different addition facts within 10 (or 66 if you count 3 + 4 and 4 + 3 separately), so every one can be mastered with short daily practice. Within 20, using addends up to 10, there are 66 different facts. Strategies such as making ten and doubles turn the second group into small steps.
