Is there some trick I never learned to multiplying decimals? I have slowed significantly on this exercise, but not for any other reason than that there are many steps to one problem.
This guy Khan is really going to change the world. I have been trying to consider how you would apply this video/exercise system to the English classroom. For test prep you could start with certain kinds of questions and run through words, definitions, and then examples and practice questions. But I don't think it will be as easy to generate these randomly as it is for the math problems. Than again, perhaps the math problems are not random. Well, that detail doesn't matter right now.
