Math Links for Week Ending Nov. 9th, 2013

If you have ever taught distance time graphs you know that a common misconception that students have is that the graph represents going up or down a hill. David Wees has made a nice little app that could help to fight that problem. Too bad it doesn't work on the iPad. But its awesome that the stick figure guy is from XKCD. Thanks to @emergentmath for this one.

It may be a pay per use but its so cheap its undervalued. Mathalicous has some great lessons. Some are free to try but the majority are only available once you subscribe. So here is one of their sample lessons on health care that deals with expected value.

I seemed to stumble on my sister site. The Ontario Math Wiki is a collaborative site where teachers can join and contribute to. Check the site out for literal tonnes of resources linked directly to the grade 7-12 Ontario math curriculum. And add your own links.

PBS Math Club is a new YouTube channel where the videos link directly to math curriculum. Some are a bit cheesey and there aren't many videos right now but there is great potential here. Right now there are just a few videos on integers. Thanks to Free Technology for Teachers for this one.

Want to try problem based learning (PBL) but don't know where to start? Well @emergentmath has your answer. They have compiled a list of activities to start with. And even though one of these is a classic calculus problem, I think that all of the problems deal with grade 7 & 8 number sense (and maybe some data management).

I totally love this video. Well, the video isn't that exciting but the concept is pretty cool. Its a 12 gear mechanism where the gears are set up so that when one gear rotates, the next gear will rotate 1/50th as fast. The last gear is connected to a cement block and due to the exponential nature of the system, will make one complete rotation in 2.3 trillion years! This is perfect for any course dealing with powers, or exponential functions.

Want a way to introduce equations? Why not solve the equation "A picture is worth a 1000 words" for one word.
