Thing #7b

I subscribe to Tipline - Gates' Computer Tips.  I read a blog about a teacher using Goggle Earth to teach a math lesson.  The students were directed to a tall building by zooming in and looking at the top of the building with a view down toward the grown.  The questions was "How tall is the building?".  They couldn't cheat because it wasn't a famous building, so they could not use the Internet to look it up.  All they had was the shadow to figure it out.  

I thought that blog was a very innovative way to teach a math lesson.  The blog also gives a site that has math lessons using the real world.
