Computational Thinking with Polyup (ISTE Gem #2)

One of my favorite takeaways from ISTE was a new (to me) app called Polyup. Polyup calls itself a "free and open computational thinking playground. Modify expressions, functions, and algorithms to discover the beauty of math." Whatever you want to call it, it's a lot of fun!

The premise is that a machine will complete computations with numbers and operator blocks. Each time the machine must be modified to get a correct output. Watch this one minute video to see how the machine operates:

It's very fun (and a little addictive) to keep modifying the machine to achieve a particular number. The mobile app comes with a game called Number Practice that has five games per level, each level with a new number goal. Number Practice is also available on the web version of Polyup and all are free to use. There are many other ready-to-use Polyup games for grades 3-12 that you can load on a device with a scannable QR code.

One of my favorite features of Polyup, though, is the ability to create levels yourself. The GIF I created above shows all the operations your custom levels can contain. You could easily use this to help your students practice some very sophisticated math. Or, better yet, you could have your students create their own levels to demonstrate their computational thinking or help their peers practice. Again, these custom levels are shareable with QR codes like these:

A little digging around on the website shows that they count Jo Boaler among their advisors, so they are getting great advice! Whatever you call it, however you use it, I think students will be engaged by Polyup and you will love it too.
