Teaching Kids Math - I

I spent some time helping my stepson with his 7th grade math homework last night. In the process, I taught him how to do work with units; e.g., treating units like numbers, calculating unit conversions via unit cancellation, etc.

As far as my own experiences go, I don't recall learning many of these techniques until some time after 7th grade, but I think these are simple and very helpful techniques that should be taught to students earlier rather than later.

There are a number of good unit tutorials for kids here and here at Drexel's Ask Doctor Math.
