What children learn in Level 3
- Expanded form shows what each digit is worth, added together.
- 5,302 has 5 thousands, 3 hundreds, 0 tens, and 2 ones. The zero tens don't need a part.
- To go back, put each part in its place. 7,000 plus 40 plus 9 is 7,049. The empty hundreds place gets a zero!
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.
