What kids do
“Fill in each row. Write the number in standard form, expanded form and word form.”
Printed on the sheet:
- Standard form: 4,562. Expanded form: 4,000 + 500 + 60 + 2. Word form: four thousand five hundred sixty-two.
Sample problems
- 6,000 + 200 + 90
- 30,000 + 4,000 +
- 900 + 10 + 8
- 90,000 + 100 +
Teacher tip
Remind kids that we never say “and” in a whole number in word form, and that commas go in the same places as in the number.
How to use it
- Read each number out loud as a class so kids hear the place names.
- Let kids use a place value mat or a folded paper chart under their sheet.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Rounding the wrong digit. Have kids underline the place they are rounding to first.
Talk about it
- What happens to a number when you move a digit one place to the left?
- Which problem was the hardest? What made it hard?
