forgive me if I’m wrong, but isn’t that one of the names this phony schooling organization used??
Khan Academy is a free, online tutoring program. We’ve just begun using their math instruction, but it’s very good.
My son clicks on a topic, say “Multiplying Decimals.” The program gives him a problem. If he completes it and enters an answer, it tells him whether it’s correct. If he doesn’t know how to do it, the program lets him look at one step at a time. Each subject also has an instructional video which explains how to solve the problems and works several examples.
To complete a lesson, he has to answer five problems in a row correctly. If he has to work 40 problems in order to get five in a row right, then he obviously needed the drill.
