What kids do
“Which place is the underlined digit in? What is it worth? Write both.”
Teacher tip
Ask for both the place and the value: the 4 is in the hundreds place, and it is worth 400.
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.
Talk about it
- Which is bigger and how can you tell without counting?
- Which problem was the hardest? What made it hard?
