The first one is an I Have, Who Has game that is dealing with concept of connecting words to expressions. If you don't know about these types of game, the premiss is that everyone has a card with a question and an answer. One student asks their question and the student who has the answer claims it and asks their question. This continues until you come back to the first person.

In this activity there is a nice mix of using dice, Desmos, foldables and portable whiteboards to look at properties of lines. This takes the tediousness out of just graphing lines.

And finally an interactive notebook (INB) on slope.

A couple of of related activities from the Making Math Meaningful blog. Related in that they both use Smarties as the catalyst. The first takes the idea of ratios, rate and linear relations to predict the price of a large box of Smarties. The second one is trying to estimate the amount of air within a Smartie box.

A couple dealing with making algebra meaningful from Jon Orr. The first one does it by connecting the idea of adding and subtracting polynomials and multiplying polynomials.... with Dora! In this 3Act task we use Dora as a unit of measure to simulate a polynomial.

In grade 12 Data Management we have to talk about probability distributions and when we do that we talk about Bernoulli Trials. That is, given the probability of failure for any individual experiment, what is the probability of failure after n experiments. That being said, it is always good to have real examples to go with mathematical concepts so here is some data on hard and flash drive failures (something that many of us have experienced first hand).

A 2013 study by cloud storage company BackBlaze looked at 25 thousand drives and found that around 5 percent failed during the first year and a half, most likely due to manufacturing defects. They were then largely stable until the fourth year, when the failure rate rose to 11.8 percent. 74 percent of drives lasted beyond the fourth year.Curriculum Tags: MDM4U

There has been a lot in the media as of late about the song Blurred Lines being a rip off of a Marvin Gaye song. So that being said, from Wired Magazine comes the attempt at answering the question "How many songs are there?" That is, given the finite number of sounds that can be produced and the number of ways those sounds could be arranged, how many different ways could you do that. Combinatorics and Wired to the rescue. Take a look here

I have shown links about the Monty Hall problem before. I like this one because it highlights how the female columnist that made it popular was correct in her analysis yet all the professors who attacked her were wrong.

The second one from Jon Orr is also about simplifying polynomials and it's based on this Mad TV skit. Totally great application of algebra (and a funny skit). Check out the entire activity here

You have all seen TED talks but you may not know there is also the TED Radio Hour. This is a radio show that picks a theme and then highlights several TED talks on that theme with interviews with the TED speakers. Recently they had a radio hour on math called Solve for X. In it they covered topics as diverse as why we use x as our main variable in algebra to the mathematics of drumming and love. See the full video of the mathematics of love below and click on the link to hear the entire radio show

These things show up on my Facebook Feed. I like them because they take patterning and put it in a friendly palatable format that most people are willing to try out
