## πLesson

### Video: Optional for Review

If your students need a review of the steps in long division, we recommend this six-minute video that uses the acronym HMS β to teach students to :

- Ask How Many
- Multiply
- Subtract
- Bring down

### Presentation on Division and Buffalo Hunts

This Google slides presentation gives common factors in buffalo hunts across different tribes and explains how whether it is computing the number of hides a horse can carry or how long each group gets to play at recess, division is always useful.

NOTE: This presentation includes two slides that reference converting a fraction to a decimal. If you have not yet introduced this concept, those slides can be deleted.
