A Hundred Times Greater
Compare digits up to 100 times greater or 1/100 as much.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 45
- Two places left is 10 times 10. So a digit is worth 100 times as much.
- Two places right is 1 tenth of 1 tenth. That's 1 hundredth as much.
- So count the places between the two digits. One place means 10 times, and two places means 100 times.
Georgia's K-12 Mathematics Standards:
- 5.NR.1.1 — Explain that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
