Khan Academy: If you haven’t heard about Khan Academy, please read my earlier blog post. Khan Academy now has an iPad app that students can use to view hundreds of math related videos recorded by Salman Khan. The benefit of the iPad app (compared to simply watching his videos on YouTube) is that the majority of the videos are broken down into small “one sentence chapters” which allows students to skip back and forth to any part in the explanations. This app could work well in an individualized classroom when you may not have enough time to re-explain a concept to one particular student, he may benefit from another explanation, and/or learns better at his own pace. While they are lots of sites that have math tutorial videos, these videos are all recorded by the same person (i.e. – consistent) and Salman Khan’s explanations are considered by many teachers and students to be top notch. Definitely worth checking out.. Free!
Wolfram Alpha: While I covered Wolfram Alpha in an earlier blog post, this amazing iPad app can bring a whole new dimension to problem solving in a math classroom. In a nutshell, Wolfram Alpha is a very advanced calculator, which you can see in these examples. Not only does the app allow you play with a plethora of real world statistics but it also allows you to solve algebraic math problems too. If you notice that a student made a mistake on a traditional paper worksheet, you can ask him to plug the math problem into the app and then use the “step-by-step” problem solver. With the assistance of the tool, the student may be able to figure out on his own (or with your help) at what step he made the mistake on paper. You can then sit down and work on the problem area together. (Thanks to Cathy Hortop for exploring these two apps with me at New Horizons, ETSB)
