Work backwards if you dare. Scholars view a video to learn how to apply the area formula of a circle to solve problems. They watch an example where the focus is finding the radius of a circle given its area, requiring the use of inverse operations to solve for r.
- Provide the video to classmates struggling with the concept
- Learners should have experience using the area formula of a circle
- Note that the video uses a TI-84 calculator; pupils must be able to find pi on their own calculators
- Step-by-step explanations make calculations clear
- Work shown is organized and neat
