Teacher Guide & Tips
- Use this key alongside the matching student handout so students can self-check their setup before computing final values.
- Discussion question: why does compounding monthly or daily produce a larger final amount than compounding annually, even at the same rate?
- Scaffold for struggling readers: have them first label P, r, n, and t in writing for each problem before substituting, using the key's variable notes as a model.
- Extension for advanced students: ask them to derive the continuous compounding limit from the discrete formula and compare results using the common-error notes.
- Estimated time: about 20 to 30 minutes for review alongside the handout.
