There is no secret of my love of Desmos so I'll start with couple of announcements. One is a new activity and the other is an opportunity. First, the new activity about scientific notation. It's a relatively short activity but it has nice visuals and has some student choice involved.

Secondly, if you like Desmos and find yourself often talking to other teachers about it, then Desmos wants you. They are looking for experienced teachers to help spread the word and present workshops about Desmos. If you want to become a Desmos Certified Presenter, then click the link below.

I like this activity from @emergentmath. It's about transversals and parallel lines. It starts with a favourite strategy of mine called concept attainment where students see examples and non examples. But the crux of the lesson is a simple activity that relates to a real map of streets. We could probably all do a similar activity using a screenshot of the streets in our own town.

I always appreciate how @MissCacul8 takes a math concept and puts some bling on it. In this case it's her kids doing a project on the unit circle by having to make a representation it. It seems simple enough but click on the link and see what her kids did. So many pies and cakes.

I've always been a fan of Open Middle problems. I think that they give students the licence to be correct with more than one way of doing things. And you can certainly get some open middle problems at the https://www.openmiddle.com/ but now @RobertKaplinski now has released the Open Middle book. This has all the info you need to get started and learn how to facilitate those types of questions.

In this video @StandupMaths tries to find the "average" person and along the way finds some issues instead.
