Usual Problem:
New plan:
Question: What is the area of an orange slice cut 3 cm from the top?
1. Give each kid (or pair of kids) an orange. Luckily, I have an orange tree.
2. Make other supplies available: string, ruler, plastic knives, plate
3. Challenge them to come up with a solution before making a cut
4. Compare calculated results with actual slice.
5. Eat the orange.
6. Students take pictures of their experiments while in progress and report results on blogs.

ReplyDelete1) size of orange to start
2) slices at different distances down from top
3) Find two slices same cross section area (but from different size oranges -> how far down was each slide from the top?
