What kids do
“Write how many hundreds, tens and ones. Then write the number in expanded form.”
Teacher tip
Say the expanded form out loud, like “300 plus 40 plus 6,” before kids write it.
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
- What is this digit worth? How do you know?
- Which problem was the hardest? What made it hard?
