Teaching a class? Give every student short daily practice, free
A printed sheet is one round of practice. A free Math Builders class adds short daily fact practice beside it, and it supplements your math curriculum rather than replacing it.
- One free class, with no student limit.
- Students tap their name at a class link. No student email addresses.
- Practice takes 2 to 5 minutes at a time, alongside your curriculum.
- Printable home cards for families, from the class workflow.
Which subtraction sheet fits which grade
Subtraction is learned after the matching addition, so use these sheets once the addition facts are stable.
Grade 1
Differences within 10 are where most children first subtract. Several come from taking away one or two, like 10 − 1 and 9 − 2, so the sheet starts easy and rises.
Grade 2
Differences within 20 are weighted toward taking from a teen. 5 of the 12 facts subtract 8, so a child who has not met the 8s will stall repeatedly, and that is useful information for you.
How long a subtraction sheet takes
Plan 15 to 20 minutes for differences within 10 and 20 to 30 minutes for differences within 20. The second sheet takes longer because children stop to think on nearly every region, not because the coloring is harder.
If your block is short, print differences within 10 as a warm-up and keep the within-20 sheet for the next day, when children have had a night to settle the facts.
Using the sheet as a subtraction center or early-finisher task
Set the center up as a check, not a race. A child colors the picture, flips to the answer key, and circles the regions that do not match. Each mismatch is a fact to redo, and the redo is the practice.
For early finishers, give a within-20 sheet to the child who finished the within-10 sheet without a single mismatch. If they have a mismatch, a second copy of the same sheet is the right next task.
Subtraction hides counting back, so check for it
The usual way to subtract at this age is counting back, and a child who counts back colors correctly. The picture proves the answer was right, not that it was recalled.
Ask a child to say the matching addition fact before they color: for 15 − 8, say 8 + 7. If the addition partner comes quickly and the subtraction does not, that is the gap. Facts that take from a teen, like 15 − 8, usually lag behind their addition twins.

Frequently Asked Questions
Each region of a picture has a subtraction problem. The child solves it, finds the difference in the color key, and colors the region with the matching crayon. The finished picture is only correct if the facts were.
When they can answer the matching addition facts without counting. Subtracting on top of shaky addition makes the sheet a counting exercise.
No. Every difference is a whole number from 0 up, and every fact stays within 10 or within 20.
Yes. It prints on its own page right after the worksheet, so you can hand it to a child at the center.
Yes. The picture picker above the sheet offers 24 pictures, and the worksheet and answer key regenerate on whichever you choose.
