- Problems involving concrete contexts, such as walkathons or lemonade stands, as contexts for linear functions
- An activity where students develop a metric for measuring steepness
- There are some good Three Acts-style problems on linear functions. Here’s one about high school graduations.
- A bungee jump experiment could be done at various points in the unit (introduction? application?) or later in the year as a review.
- This is a good problem: using dice stacking problems to get at linear functions.
Still looking for:
- A good experiment that doesn’t take up too much time but also helps foster an intuition for linear patterns. Maybe Dan’s airline ticket activity? (Computer lab is a problem for me.)
- An activity that moves from satisfying equations by guess-check to developing a technique for finding more points to developing slope.
