Teacher tip
Kids can jump in any size chunks. Celebrate different paths that land in the same spot.
How to use it
- Warm up with two minutes of facts out loud before kids start.
- Ask kids to circle the problems they are sure of first, then go back to the tricky ones.
- 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?
