### Math Links for Week Ending July 22nd, 2016

This is a kind of fun site. Some math games that reach different strands. I like Square It but I think Factors and Multiples Chain might be my favourite. Here you choose numbers from 1-100 and try to create chains of numbers that are either factors or divisors of each other. Good practice for factoring. There are more than these two so take a look.

Of course, now that Desmos has their Card Sort feature, there are some good ones being produced by the math community. Like this one, for example, from @mathycathy about sorting statements about real and rational numbers. It's short and sweet and it starts to show some of the different ways you can do sorts with this new Desmos feature.

It's always good to have more fun examples of projectile motion. And with a video title like "Human Slingshot - BASE Catapult | 0-200kph in 1 second" that means the analysis from @rjallain (see the link) will be pretty good.

I love this one from @standupmaths where he shows that the current Euro 2016 soccer ball is actually based on a cube. Some cool 3D tessellation here.

It's always good to see math show up in real life, though this might be a bit of some "bad press". Still, there might be a lesson on percent that could be wrapped around this image from @mburnsmath.
