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

I have various card sorting ideas I’m still working on for energy. These are some of the cartoons that have arisen as part of that work.

Early Draft of an Energy Card Sort – just playing with possibilities right now.

Just sharing some cartoon drawings I made for students practicing identifying energy transformations.
