Instructional Ideas
- Create more difficult problems than those in the video for scholars to work on their own
- Review metric units if pupils aren't comfortable converting from cm cubed to dm cubed
Classroom Considerations
- Sample problems should not require a calculator to solve, but the resource does assume prior understanding of multiplication and division
Pros
- Provides prompts to pause the video to solve questions before learning the correct answer
- Stresses the importance of labeling units when performing calculations
Cons
- None
