What kids do
“Look at the digit to the right. 5 or more? Round up. 4 or less? Round down.”
Printed on the sheet:
- Example: 4,672 rounds to 4,670 (nearest 10), 4,700 (nearest 100) and 5,000 (nearest 1,000).
Teacher tip
Draw a quick hill: numbers 5 and up roll over to the next ten, 4 and below roll back.
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?
Take it further
Have kids find big numbers in the newspaper or a fact book and write them in expanded form.
