Powers of Ten
Write 10, 100, and 1,000 as 10¹, 10², and 10³.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 46
- Writing lots of 10s gets long, so mathematicians have a shortcut. 10 times 10 is written 10 with a small 2. We call the small number an exponent.
- The exponent tells how many 10s are multiplied. It doesn't mean multiply by 2.
- Here are the three powers of ten we'll use. Notice the exponent matches the number of zeros.
Georgia's K-12 Mathematics Standards:
- 5.NR.1.2 — Explain patterns in the placement of digits when multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10, up to 10³.
