Strategies for Larger Numbers
Mrs. Dewey then asked her class about numbers larger than 100. She said, “Do you think you can multiply a number that is larger than 100 by using the same strategies?”
She wrote these problems on the board for her students and asked them to solve the problems using whatever strategy they chose.
| 150 3 | 6 299 | 403 5 |
| 248 2 | 140 10 | 5 440 |
Here is what some of her students had to say.
- Solve these problems using any strategy you choose:
- 601 4
- 666 5
- 198 7
- 643 10
