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.

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.

If you haven't been listening to the @MathTeacherLounge podcast then you've been missing out. The good news is that with podcasts you can always get caught up. The bad news is that they just published their last episode. Sad to see its on the way out but was happy that @DDMeyer and @LockhartEDU were able to give us 3 seasons. They were a great team.

@Howie_Hua manages to put out a lot of content (on top of his actual job of teaching preservice teachers) but I really like the recent few that he's put out about small changes you can make that can affect big changes. Here's the 4th one (you can search his feed for the others).
