Math Links for Week Ending May 27th, 2014

I have actually got a lot of data sets that I have to post about on my Found Data blog. On this blog I highlight data sets that can be used to teach stats and put them in an easily downloadable form. This set comes from Ontario gas prices and was pointed out to me by Michael Lieff. There is actually 25 years of data available in one year chunks, but I was able to download all the data in one place here.

This is a really simple activity from @natbanting's blog that can be used to help student practice order of operations. You set up the structure, then roll the dice and students try to make an expression that is either really big or small etc. One thing I like is the rule about students having to place the numbers as they come without waiting until all appear.

Personally I use a similar product called Nearpod but have been intrigued by Peardeck. There are some features that Peardeck has that Nearpod doesn't and vice versa. At first glance, though, it seemed like Peardeck's features that I liked only existed in the paid version. However, I was intrigued by some of the features that @wheeler_laura pointed out in one of her recent sketchnotes
