How to use it
- Build the first number with base-ten blocks before kids write anything.
- Draw a place value chart on the board and keep it up while kids work.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Zeros as placeholders. Kids often write 307 as 37 or three hundred seven as 3007.
