About this worksheet
Three numbers live in each roof. Write the two addition and two subtraction facts they make.
What kids practice
Subtraction is finding how many are left, or how far apart two numbers are. Within 10 means every number in the problem is 10 or less. These facts are the base for every later kind of subtraction, so it is worth getting them solid.
Watch for
- Counting the starting number as the first hop when counting back, which gives an answer one too small.
- Subtracting the smaller number from the larger one no matter which comes first.
- Guessing instead of using a strategy. Ask "How could you check that with addition?"
It's free to print, with an answer key. See the full subtraction within 10 guide for 1st grade.
