Math Links for Week Ending Feb. 2nd, 2018

Last week @MrOrr_Geek had a post on different ways to use two truths and a lie and this week @desmos has their version. Although I don't think this is a particularly useable at this point but it does give us a sense of what might be coming in the future from Desmos. For now These two activities can only be used from the student perspective (there is no public version yet). Still though, it's a neat concept. You, as a student, creates an image and then writes two truths and a lie. It then goes in the gallery.  Then you can look at any of the others in the gallery. Give it a try, there is an elementary (fractions) and secondary (parabolas) version.

Looking at introducing solving logarithmic equations? Then you might want to start with this simple activity for giving students a feel for the way powers work from @sqrt_1. And I like the idea of using dry erase sleeves to save on paper.

Okay this is a long video but the end shows a crazy connection to Pascal's Triangle
