I’ve been slowly working on some tasks for supporting algebraic reasoning about proportional relationships, inverse relationships, and quadratic relationships. We’ve been noticing that we really need to better support this in the 1st semester so that when it becomes more serious in 2nd semester, students have had more practice.
Anyway, this is just a dump of various drafts. Mostly they are intended to be Ranking tasks (like TiPERS but in a card sort format). I can imagine using some of additional the matching cards as scaffolding. I probably wouldn’t include them all the time, but it might make sense early on.
I have others in the mix, but I just wanted to share at least some to let people see.
Given Force and Mass: Rank by Acceleration
Given Distance and Time: Rank by Speed
Given Speed and Mass: Rank by Momentum and then by Kinetic Energy
Given speed and acceleration: Rank by Duration (then Distance)
For Circular Motion: Rank by Net Force, Acceleration, Period
Given speed and time: Rank by Distance
Rank by Change in Momentum
