What kids do
“Use the three numbers to write two addition facts and two subtraction facts.”
Teacher tip
Ask which number can never be first in an addition fact. It is the whole, and it starts every subtraction fact.
How to use it
- Ask kids to circle the problems they are sure of first, then go back to the tricky ones.
- Keep a number line or hundred chart taped to the desk for kids who need it.
- 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
- Which answer could you check by doing the opposite operation?
- Which problem was the hardest? What made it hard?
Take it further
Turn three problems into story problems and illustrate one of them.
