What kids do
“The little number tells how many times to multiply by 10. 10³ = 10 × 10 × 10 = 1,000.”
Sample problems
- 9 × 103 =
- 80,000 ÷ 103 =
- 8,000 ÷ 102 =
- 9 × 102 =
- 3 × 104 =
Teacher tip
Ask kids to write 10³ the long way (10 × 10 × 10) for the first few.
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?
