Warmup and cooldown for EV2 #373

Closed jkostiuk closed 2 months ago

jkostiuk commented 2 months ago

Here is my suggestion for warmup and cooldown for EV2, addressing TeamBasedInquiryLearning/library#28 . Let me know what you guys think.

For the warmup, I wanted them to think in terms of analogies to build some language fluency. The activities in EV2 do a good job of having students get into the computations quickly so didn't feel it was needed in the warmup.

For the cooldowns generally, I want to avoid them doing straight practice--the CheckIt problems already do that. I'd like them to instead flex some adjacent muscles we don't workout in the activities. For this one, I thought proving the fact that we need at least n vectors to span R^n would be a good way to both reinforce the concept, and has the added benefit of making it clear that (a) we don't prove the fact and that (b) they are capable of proving the fact.

This is my first time trying to make a branch and create a pull request on my own. Please let me know if what I did was an acceptable workflow.

This is the right workflow. I noted a typo above, but instead of just fixing it I left it for you to practice making additional changes: if you commit a fix to the same 'EV2-WarmupCooldown' branch then it will show up here.

One other thing, since this is in part addressing an open issue, you should include a comment like "Addresses TeamBasedInquiryLearning/library#28" in your PR text, so that it gets linked back to the issue.
