A few weeks ago I mentioned the Mathies.ca site and mentioned that I would be revisiting it. The site is developed for students and parents but I think its important for us to know what is there to let them know. There is mention of older resources but I want to focus on some of the new stuff in the Games section. One that I think could have a lot of traction is the card matching game. Basically its the classic flip cards over to make matches but there are different versions for different topics. Currently there are versions for whole numbers, integers, fractions, linear growing patterns and trig functions. Give them a shot. Note that you can even download these apps to embed in your own sites or Notebook files.Curriculum Tags: Gr7, Gr8, MPM1D, MFM1P, MCF3M, MCR3U

A few weeks ago I mentioned that Simon Singh had a new book out about how math is infused in The Simpsons and Futurama. Listen here to an interview with Simon on what is in the book.Curriculum Tags: All

Thought I would just quickly mention this. There is a movie being made about the life of Ramanujan. He was the Indian prodigy that was self taught and was around earlier the 20th century (Simon mentioned him a bit in the above piece. So look forward to this when it comes out.Curriculum Tags: All

It is always neat to find real world examples of math showing up. Here is one from the fashion world and patterning. Thanks to @bucharesttutor for this one.Curriculum Tags: Gr7, Gr8

"It's funny because it's true"- Homer Simpson. On the Math with Bad Drawing blog a great post about actual (or simulated) headlines from the world and what the actual interpretation is (with bad drawings of course). One of my favourites: Actual Headline "Market share of electric cars triples" Interpretation from the math world: "Market share of electric cars rises to 0.4%". This is a perfect starter for conversations in any data management class when you have to talk about media literacy.Curriculum Tags: MDM4U

So earlier last week my friend Mark sends me an email asking me if I could solve for these angles. Looked like a harmless question. Turns out it wasn't solvable. After crunching the algebra and continually getting 0 = 0, I resorted to some sort of visual proof. Then I thought of trying out Math Disk since now I had a reason to. So here is my sketch. See if you can use it to determine why its not solvable.Curriculum Tags: MFM1P, MPM1D

I like this app for working with three term equivalent ratios. Its kind of contrived but I think its kind of interesting how it tries to relate the "developing" to the ratio. If you search around this set of apps from Alberta Math you will probably also find some other stuff you like.Curriculum Tags: Gr7, Gr8, MFM1P, MPM1D

I never miss an opportunity to plug the Museum of Math. I hope that one day when I get back to NYC I will be able to go there. But in the mean time I will have to settle for articles about all the cool "Mathie" things they do in the community. In this case, its about Pythagorean theorem and the famous Flatiron building to celebrate Pythagorean day (5-12-13 hmm when will the next one be?). I didn't realize there was such a connection to that building. You can read about that here. Thanks to Mark Esping for this one.

I really like this video on conditional probability from Art of the Problem. I am a big fan of tree diagrams and this does a nice twist on the coin flipping problem by introducing unfair coins.

And why not one more from Art of the Problem. This time on standard probability

So my friend Michele pulls out this holiday Toblerone and its a hexaganol prism. "Sweet" I think and snap a quick picture and post it on Twitter. Low and behold, seconds later its retweeted by a tweet-bot @Hexagonbot "Hexagonbot is an automated hexagonal information service brought to you by the Global Hexagonal Awareness Project. ". Ha ha, the global Hexagonal awareness project. Nice. Turns out they have a site devoted entirely to hexagons and the bot scours Twitter for key words relating to hexagons and automatically retweets them. They are up over 320,000 tweets, all about hexogons.
