Algebra and Geometry both had work days today.
Geometry is in a weird place… Half my students know all the formulas for volumes already and the other half appear to have never have seen them before. Also, I don’t know any of the tricks to help students remember the formulas. We watched a few videos on where they come from but most are just a step away from pretty intense proofs involving limits.
I need to provide some concrete examples of where the formulas come from. Maybe fill a pyramid up with some liquid and pour it into a cube with the same base? Let me know your strategies for helping students derive volume formulas.
