Math Links for Week Ending Dec 28th, 2018

If you are working on Pythagorean Theorem with your students then this exercise might be a nice self checking activity. Take the numbers from 1-10 and pick any two, use those as the legs of a right angled triangle and calculate it's hypotenuse. Scratch out the two numbers used and add the hypotenuse to the list. Repeat this process (you should be able to do it 8 more times. The neat thing is that no matter which order you choose the numbers, you will always get the same last value. I will leave that value up to you to figure out. Thanks to @JamesTanton for this one.

Some nice ideas from @TheErickLee on modelling quadratics. I like the idea of physically demonstrating the nature of quadratics with a punctured water bottle and then snapping a picture and graphing on Desmos.

If you want your senior students to be good at modelling then you have to give them opportunities to model things that may not be obvious. In this activity @ChrisHunter36 does that and get's some great results from students.

If you haven't heard of 2018's newest shape the scutoid, you're missing out. Here @ViHartViHart has some fun with scutoids and if you follow the link below you can get to her page with a net you can download to create your own. And as an added bonus, if you have a set of VR goggles, this video was recorded just for them.
