Here’s a tidbit I created for students to reference during our 3-D geometry unit. I had some trouble finding iPad-friendly links to interactive resources because so many are flash-based. Nevertheless, I really like the way ThingLink handles video links! Very cool!
I plan to have students analyze the way the formula is presented for the volume of a sphere… syntax when typing fractions without an equation editor may change mathematics unintentionally! Rather than omit the resource, I think having a meaningful discussion about the formula might be mathematically rich and worthwhile.
Feel free to use or share!
Additionally, here are some graphics I created that help students “break down” the formulas to find the lateral and total surface areas of cylinders and prisms. Enjoy!
