I’m really excited about the potential of a new app called MathChat. It is an app that allows students to key in problems, start to solve them, and when they get stuck have their peers comment and help. It is kind of a mobile version of the OpenStudy website. A couple of perks: as students work through expressions/equations, MathChat checks their work line by line. It only tells them if it is equivalent or not. The student still has to find the mistake and fix it. Also, MathChat uses the touch capabilities of the mobile environment, so that peers can give you help by writing on your problem. This is a real nice touch. It is early and I haven’t really had a chance to test drive this app with students, but the app holds a lot of promise.

I got to demo a great new product last week. It is called Mathspace. It is both a web and mobile app, and the real innovation is their exercises allow you to write and check intermediate steps. And their handwriting interpreter is the best I’ve seen. It is a little hard to explain exactly what I mean. Check out the gif above.
There are other perks like adaptive learning, videos, badging, and a gradebook, but it is the above feature that really sets the app apart. The company is young and adding content. Definitely something to watch out for.

Math and Twitter

What can a math teacher find out about math from Twitter? I loved this Deb Costello post. I used to do the same thing before google shuttered real-time search. I loved pulling up “math” at the beginning of my classes to see all the post/updates that rolled in. It was always good for a laugh.

Mobile is Coming…Finally!

I just got back from the ICTCM math/tech conference. I had a great time and learned a lot. Two things I wanted to pass on. Both MyMathLab and Mathematica are going to be viewable on mobile devices. I had actually heard about MyMathLab for a while now. The news about Mathematica was new though. I’m really excited because you can create such amazing manipulatives for students. The problem has been that those manipulatives have been locked into Mathematica’s CDF format. And admittedly anyone can get a CDF viewer for free by downloading, but who wants to deal with that! I’ll be implementing it in my online classes a ton now.

Building Estimation Skills

Estimation 180 is a great site for building estimation skill. I can see using this at the beginning of class to stimulate thought. Best of all the site works great on mobile devices.

MyScript Calculator

my script calculator

I recently downloaded the MyScript Calculator app. Some of you may have seen it on one of the iPhone commercials. It is the app that you write an expression and it recognizes the expression and typesets it perfectly. At least that is the way it works in the commercial. I think I suffer from fat fingers and poor handwriting because it doesn’t work quite as well for me. The idea is fantastic though, particularly for more complex expressions like CodeCogsEqn (13) that are easy to write, but hard to enter into your regular scientific calculator. Here is how it is supposed to work.

I hope the recognition improves. And it is free so I really shouldn’t be complaining at all. Here is the download link for iOS and android. Give it a try.

The App I’ve been waiting for…

dragon box
There are a ton of great mobile apps that are beautiful, smart, and addictive that teach arithmetic and number sense. What I’ve been waiting for is an app do the same thing for algebra. Dragon Box is the first. It doesn’t handle the whole curriculum. It is really just focused on solving linear (and basic rational equations), but when you start one would never even know it. That is what is so awesome about it. It starts much like any other mobile game with some tutorials on the game’s dynamics. There are no x’s, no numbers anywhere. Slowly as you make it through the levels, the moves you make in the game start to be recognizable as the manipulations one does to solve equations, and the objects start to become numeric, and at the very end the variables start to appear. It is extremely well done. I encourage anyone interested in gamification or mobile ed to check it out. It’s a little expensive at $6, but for the first of its kind, it is worth it. I don’t regret buying it. I also hope WeWantToKnow is hard at work on other algebra games.

Pondering Future Math Classes

I was blown away by this WolframAlpha demonstration in one of my feeds this week. It led me somewhat tangentially into a discussion with my College Algebra class about the future of math classes when algebraic solvers become as prevalent as the four function calculators everyone has in their “dumb” phones. If that prospect isn’t scary enough for math teachers, check this out. Natural language queries using Siri. Yikes!

The only part of my current assessments that is safe (for the moment) is the applied (word problem) section. Time to think up some new questions.

Math + Ipad

I’m kind of an Ipad app addict. There are tons of great teaching tools for the Ipad, but I’ve had more trouble finding games for math. The best one so far is Symmetry Shuffle. It is visually well done and mathematically challenging. I only wish I could play it on Game Center with my students :(

Let me know in comments if you have a math game you like. Particularly if it is multiplayer or has a Game Center like component.
