### Math Links for Week Ending Mar. 23rd, 2018

Well it has taken weeks but my partner in crime (Gisele Jobin) and I have finally completed this video. We have talked about doing it for a while but it seems it has finally got done. We wanted to develop a progression of questions to develop the fraction multiplication algorithm. Of course we know that it's the kind of thing that is so easy to tell students then let them practice but like many other things that students are told, they mix them up with other things and rarely ever understand them in the first place. So this longish video is our way of encouraging you all to develop the algorithm instead of just giving it to them. We used the Mathies Fraction Strips app but any sets of fraction strips will do. Next up is the fraction division algorithm.

Here is a nice little short puzzle/sorting activity for types of polynomials from @mathequalslove. Students are given a deck of polynomial pieces and some cards with types of polynomials (eg Cubic Polynomial). And they have to place all the cards to create polynomials to match.

I don't think we can have enough resources to help us understand students with learning disabilities. Here is a very comprehensive resource on ways we can support students with LDs. Thanks to @kmarkpet for this one

I've had division of fractions a lot on my mind lately so I think this post from @MarkChubb3 about how context can make the difference in understanding. I really like the beginning with the conversation with his wife that really brings it to light.

An offshoot podcast from Planet Money is called The Indicator which is a short look at a number in the news. This episode was 1994 which is the year graphing calculators were allowed to be used on the SATs and one of the things the podcast talks about is why the price of the TI-84 has essentially stayed unchanged since it's inception.

On this episode of Note to Self they speak to @MonaChalabi who is the data editor for The Guardian who does some very cool stuff both in the publication and on her Instagram feed. She picks interesting data sets and creates interesting visualizations to represent them. Listening to a podcast doesn't do her work justice but listen at the link below and then and then check out her feed.

This is not a new article and not new info but it's worth reminding ourselves that there is real research behind the idea that if students feel they have some choice, they will do better, especially in math. Thanks to @KMarkPet for this one

@mathletepearce is hard at work with his new site Math is Visual and has added another video on multiplying integers. Watch the video but also follow the link to get the full annotations for the video
