### Math Links for Week Ending May 18th, 2018

So last week I was tagged in couple of Tweets from @MathGeek76:

What followed is Twitter to the rescue. If you look in the comments to those Tweets then you will see many new versions of the original activity (see the first tweet for the original student version). And honestly I don't know where the latest version is now but I love the fact that how the versions show all the collaborators. It's turning into a nice little activity about estimation with some nice data management themes. Way to go Internet.

There is a new resource in the Capacity Building Series. This one is on Fractions across the Curriculum. Fractions research is showing up all over the place now. It's good to know that we are on the forefront of this here in Ontario.

This reminds me that you don't have to make a grand activity to help students make sense of the world. Sometimes you just ned to ask the right question(s). Here @MrOrrGeek takes a simple question and then digs deep into proportional reasoning. Take a look

I posted some of this last week and although @MSBJacobs intended this to be for grade 6 students, I think you can use this with all students grade 6 and above to help students get more comfortable with fractions. By using Open Middle style questions, this helps students do these and be correct in many ways. And one simple thing I like about these is how he uses these number tiles to help students only choose a number once.

An interesting puzzle connected to Pythagorean Triples
