A new resource from @mathletepearce called mathisvisual.com combines some concepts in number sense starting with counting and currently ending with adding and subtracting integers. And all done visually. I am sure there will be more to come but take a look at what is there so far.

Thanks to @MSBJacobs for pointing out this site. It's for Chalk Dust Magazine which is "A Magazine for the Mathematically Curious". Many great articles and puzzles. And if you are quick you can enter the current Christmas based puzzle for a chance to win a copy of The Indisputable Existence of Santa Claus by Hannah Fry and Thomas Oléron Evans

It's never good to here that students lack confindence in math but it appears that this is more prevalent with girls.

I like when @ddmeyer releases his yearly talk video. In this one the theme is that "math is power, not punishment". That is, we need to do a better job of convincing students that it is worthwhile to know about math. There are some nice examples and even some Ontario teachers make a brief appearance (@MrOrr_Geek, @AlexOverwijk and @Wheeler_Laura). Definitely worth a watch.

Some nice interactives from @dpscher on arrays and a nice video to go along with it from @JamesTanton giving a reason to use arrays in the first place (including for algebra)
