AP precalculus ss started class debating "What is the best way to represent a function?" 🤔 - The overall agreement was that it depends on the task (Source B. Passwater) @chappaqua_csd

Select a square of numbers on the main diagonal of the multiplication table. Take the sum and difference of the two different-valued corners and the sum of the same-valued corners.
c=9+49=58
b =49-9=40
a=21+21=42
Then a^2+b^2=c^2! Why?
Does every Pythag triple appear this way?

What's in your piggy bank? 🐖

Explore this Problem to Ponder involving piecewise functions to consider the impact of replacing coins.

A great opportunity to discuss domain, range, & the maximum amount of money that would be possible!

Hey teachers, have you done the “put vinegar in a cylinder, put baking soda in a balloon, attach it to the cylinder, tip up the balloon & watch it inflate”
Upscale it by having students:
✅Use a scale & test different amounts of soda
✅Use flexible tape measure & find balloon circumference
✅Switch soda & vinegar location
