What kids do
“Subtract. When the digit is 0, borrow from the next place over. Check by adding!”
Teacher tip
Teach one approach, like regrouping 400 as 39 tens and 10 ones, and stick with it for the whole sheet.
How to use it
- Use it as a timed sheet once a week and have kids chart their own score.
- Let partners check each other with a calculator after they finish.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Columns that drift. Turn lined paper sideways or use graph paper to keep digits lined up.
Talk about it
- How can an addition fact help you solve a subtraction fact?
- Which problem was the hardest? What made it hard?

Turn three problems into story problems and illustrate one of them.
