You may not be into doing Twitter chats but even if you don't like to participate you can still reap the benefits (even if you don't have a Twitter account. It may take a little time to get used to that mode of discussion (basically a stream of conscious) but you can read the stream at any time. Just this week there was a Twitterchat for the hashtag #swdmathchat - that is students with disabilities math chat. They posted 8 prompts and people would then respond to them. A lot of good things discussed on this week's chat. and more to come in the coming months.

Just in case you missed some of these, @fivethirtyeight has compiled 45 of their best and weirdest charts from the year. Even though they do a fair bit of politically based graphs, there are enough sports and other pop culture related data to make things interesting for students.Curriculum Tags: MDM4U

I created a dynamic tessellation that falls apart but can be put back together.

Playing with #Tessellation using @Desmos #geometry. First slide some points & the tessellation falls apart (but looks cool). Slide some more points & it brings it back together for a similar tessellation.— David Petro (@davidpetro314) January 9, 2019

I think it is hugely important to give students hands on experiences that help develop their spatial reasoning skills. This video is part of the reason why

I videotaped this student (someone who rarely sees success in math class) engaging in a spatial task. Just watch her face in the final moment of solving the task: #ElemMathChat #SwDMathChat pic.twitter.com/oJM81COQ1L— Mark Chubb (@MarkChubb3) January 11, 2019
In advanced functions when you are talking about combining functions, if you connect that with sound waves (I used to do that) then this video is a nice application of those wave additions.

Lots of new podcasts episodes. They guys at @MakeMathMoments have added their 5th & 6th episode. They spend an episode helping a teacher manage her resources and also do a great interview with @JamesTanton who makes you want to do math no matter what mood you are in.Curriculum Tags: All

There have been a bunch of new @MyFaveThm episodes but only a couple of them feel like they could have some relevance to secondary school math. One comes from @stecks who talks about her 1 cut theorem that she did on @numberphile. Fun stuff. Then the episode on Assigning a value to Teamwork. And although, at first, it may not seem like it connects to secondary math, later in the episode @anil_venkatesh talks about how he uses these theorems to design video games. Something some of your students might be interested in.Curriculum Tags: All

Finally, we released our second episode at @OAMETalks. This time with @Marian_Small. It was a fun conversation that served as a preview to her webinar. One of my favourite parts was when she said: "If you personally are uncomfortable with a piece of the math you have to teach....now you are the teacher. And you owe it to the students that you teach to now take the professional responsibility to learn that stuff that you didn't learn."Curriculum Tags: All

Do you want your kids to learn about Domain and Range but have fun doing it? Or even if Domain and Range isn't the focus and linear equations is, this works too? Why not have them create their names using straight lines?

This simple prompt can get your kids solving quadratic relations (if they choose to do it that way)Doing some cool things on @Desmos in Algebra 1 to kick off 2019!
