This unit culminates in students proving the exponent properties for zero, negative and rational exponents. It prepares students for studying exponential functions.
- Chris Lusto uses a counter-intuitive folding problem to introduce geometric sequences.
- Paul Solomon has a good problem that helps students discover and prove the properties of exponents.
- CME Project has a very clever way to to think about fractional exponents as partial multiplication.
- Park Math and David Cox have somewhat complementary approaches to getting kids to grapple with fractional exponents, and their connection to radicals.
- CME has a brilliant way of thinking about rational exponents.
Here’s everything posted under ”Exponents,” including stuff that didn’t make the cut.
Still looking for:
- Some more good problems that allow us to prove that certain exponential expressions are equal to radical ones.
- Simplifying radicals
- Arithmetic with rationals
