Math Links for Week Ending Mar 29th, 2024

Seeing this list of math videos by topic makes me think that I should look back at my old BlockBuster Math presentation about Math in Movies and TV. I literally have tonnes of clips on a hard drive that must exist other places. Gives me something to do in compiling that.

I like this because you could solve it rather elegantly with algebraic manipulation or use a more brute force method by just evaluating the powers.

My comment about this is that this is now the nail in the coffin for traditional teaching (just telling kids stuff)

I made this investigation to look at various circle theorems. However, I made two versions. One that requires much more construction and one that has far less (so it takes less time). Get them both at the link below:

The thing I like most about this is the fact that it shows that, for the most part, effective teaching has bits of all the researched based ideas in proportions based on you. And those proportions vary from person to person when it comes to what is effective. But regardless I like @Jason_To's even keel treatment of this.

I like a little app like this for practice. We are all interested in multiple representations of linear relations. So it's nice to have a practice problem like this with randomized problems and constraints.
