Math Links for Week Ending Mar. 31st, 2017

I love this site (that is new to me) called Graph of the Week. Kathy Turner has been showing her kids a graph of the week for years but now has some of her collection on this site for the rest of us. Each graph (or set of graphs) comes with some possible questions for prompts for students. Thanks to Janet Jacques for this one

This is a common application of Pythagorean Theorem to compare sizes of TVs, but it is always good to see practical applications of math. In this case it's linked specifically to phone screen sizes. Thanks to @MatthewOldridge for pointing this one out.

Need to have your kids practice graphing points? Why not give them this Desmos Marbleslides where they play "golf" by plotting points.

Another one from @standupmaths with bricks. This time it's that classic physics problem of stacking bricks so that the overhang of the last brick is beyond the first. Though the premiss of this is based on centre of mass, you can do some mathematical modelling with the result. See this Desmos sketch to see how.

Building a thinking classroom is a great idea. And @Wheeler_Laura has some great sketch notes to help you along. I showed some a few weeks ago, they are at this link and more along with a lot of other ways to change over to a thinking classroom.
