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.

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.

You have to have a bit of a thick skin but everyone should take part in this #ObserveMe activity. We cannot teach in a bubble and the only way we will ever be able to get better is with feedback. And we don't get feedback if we are the only ones in our classes as we teach

So I knew that Geogebra could be used for 3D graphing but I didn't know that Graspable math was connected to Geogebra so that you could do some on the fly dynamic stuff. Nicely done.

@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).
