What children learn in Level 4
- A number can be shown in many ways. 163 is 1 hundred, 6 tens, and 3 ones.
- Break the hundred into 10 tens, and 163 is 16 tens and 3 ones!
- Or break a ten into ones: 15 tens and 13 ones. It's still 163.
- 568 is 500 plus 60 plus 8, or 500 plus 50 plus 18. Both make 568!
- Big numbers too: 2,300 is 23 hundreds, because each thousand is 10 hundreds.
Georgia's K-12 Mathematics Standards:
- 3.NR.1.1 — Read and write multi-digit whole numbers up to 10,000 to the thousands using base-ten numerals and expanded form.
