Here is a great dynamic bar graph that shows how the value of the largest companies of the world has changed since the year 2000. What do you think will come out on top by the end of 2018. But after seeing this video lead me to this site called Interbrand which is where they got the data. It has has all kinds of interactive graphs dealing with the popularity of brands. Thanks to @Robin_Grondin for pointing this one out.Curriculum Tags: Gr7, Gr8, MDM4U, MBF3C

It seems that I am getting caught up on @mathequalslove's blog this week. You can always count on her to create activities that take the standard worksheet and turns it on its head to make things more engaging for students. In this case it's a puzzle worksheet for trig identities.Curriculum Tags: MCR3U, MHF4U

This posts tackles the idea of dividing polynomials using long division or synthetic division but really it's about her activity to use box division using cards. She uses them in combination with her clear pockets to help students with this mechanical mathematical method.Curriculum Tags: MHF4U

In calculus we are always trying to conceptually convey what is happening when we are determining the derivative and finding the slope of the tangent. The main concept is that the slope of this curve is being measured using a straight line. That can be confusing to some students. To help that @DavidBulterUofA and @aknauft have built this Desmos sketch that "magnifies" any part to show that if you zoom in enough, any curve can be approximated as a straight line.Curriculum Tags: MCV4U

In the latest @Numberphile podcast episode, you can hear the interview with @SimonSingh and among other things, he talks about his new website that gives weekly challenge problems to math students. Students and teachers can create accounts on the site so they can "Be challenged, get curious, do maths. Stretch your brain every week."Curriculum Tags: All

There are certainly people that think that it's important for students to learn algorithms. In my opinion there is no problem with learning algorithms but it shouldn't be the first thing that students learn about a topic and it certainly should be the goal of the learning. In this post @MBurnsMath shows (through student conversations) that algorithms are certainly not enoughCurriculum Tags: All

Any data management or statistics teacher needs to look at all types of data representations. Heat maps are a neat way to look at data on a gradient and if you can also connect that to lat/long data to map that out. Here's how to do it with CODAP

The boys @MakeMathMoments have been busy with their new podcast. They have been putting out quality episodes one a week since before the new year. There are your standard interview type episodes with people like @JamesTanton, @mathforlove and @JoBoaler but the ones that I like the most are the Mentoring Moments episodes where they talk to a teacher from somewhere in North America and try to help them with their particular teaching issue.Curriculum Tags: All

We've been busy at the @OAMEtalks podcast with a new episode from @FawnPNguyen and a couple of episodes of previews of featured speakers for OAME 2019 ( @LLB_315, @jboninducharme, @gfletchy, @eluberoff, @carloliwitter, @NatBanting, @stoodle & @samjshah2). We have one more OAME 2019 preview episode planned to come out on Monday (with @davidcampbell, @TracyZager & @JenniferWilson) and our last regular podcast of the season coming out March 1st with @MarkChubb.Curriculum Tags: All
