iPads in the high school math classroom

My district invested in several classroom carts of iPads this year. This will allow us to have one-to-one computers in the classroom during selected periods; we sign up for the carts ahead of time, just like booking the computer lab. They are not personal devices for the kids to use outside of class, so we won’t be ditching our textbooks yet. Teachers also received training and their own devices.

I am not particularly interested in apps to practice solving equations or other drill-in-a-fancy-box. (Most of the vainglorious ly advertised “math-teaching” apps seem to fall into this category.) I’m seeking ways to use the devices strategically to get deeper into the mathematics. So far, I have the following uses in mind:

  • Desmos, a free online dynamic graphing calculator that works well on the tablet. It’s easy to imagine using this. I have an in-classroom set of TI-84s, but Desmos is better for many applications. For exploring how the coefficients of a quadratic effect the shape of its graph, Desmos would be smooth as okra in gumbo.
  • Google apps with the iPads as data collection devices, to build spreadsheets of school data for analysis in class. We’ll be doing the data unit in Algebra 2 pretty soon, so this may be my first foray with the class iPad cart. Kids will write their own survey questions, which must be clear, quantitative, and Hemingway-esque. Then they’ll use the iPads in conjunction with a spreadsheet/survey to get data from students around the school.
  • The camera – still and video – with share-ability for a variety of purposes.
  • LogoPlus is a nice, clean Logo programmer which I would like to get kids using. Being good, it is not a free app, which creates a bit of a barrier for the classroom set. I have not found a free Logo app that I like. (Does anybody use Logo in high school geometry? I really want to!)
  • I can imagine students using ShowMe or something similar to demonstrate their understanding or facility with particular procedures. Maybe. Actually this could make a nice assessment, in the right context, but there are some issues with how the files are saved and stored.

That is kind of a short list! In the future category:

  • Geogebra for iPad is in development; I am really itching for this one. Right now the closest thing out there I know of is this: http://tinyurl.com/ggbweb/ but last time I tried it on the iPad many key functions didn’t. (Sketchpad Explorer is a dud for high school IMO – too limited in functionality.)
  • Mathematica folks told me they have an iPad version in the works, which should be interesting to see.

Anybody out there have wonderfully enriching uses of iPads in secondary math classes? Please get in touch in the comments! Thanks.

    Paul, I love your blog! I read all your entries. I too entered teaching after various careers in industry and I have followed blogs surreptitiously..until now.I’d love to get my kids programming. I will be watching for iPad ideas from you; my math department will be getting them next year. Desmos is very cool — I found the sliders I want — but Logos is yet a dream. Keep writing, please!
