Ideas for using these sheets
- Build each number on the first sheet with real blocks, or with bundles of ten straws and loose ones.
- Say numbers the long way out loud: 352 is 3 hundreds, 5 tens and 2 ones.
- Point out zeros: in 405 the 0 holds the tens place, so the 4 is still worth 400.
- Turn an expanded form answer back into the number to check it.
Every setting can be changed above before you print, and “New problems” makes a fresh sheet as often as you like.
