Estimate the Quotient
Use friendly numbers to predict the answer.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 26
- An estimate tells you the size of the answer before you start. Take 3,276 divided by 12. Find friendly numbers near them.
- 12 is near 10, and 3,276 is near 3,000. That's 300.
- So the quotient should be in the hundreds. Our answer, 273, fits. An answer of 27 or 2,730 wouldn't.
- Multiplying checks a guess too. Is 1,000 groups of 12 too many? Yes, that's 12,000, far past 3,276.
