[quote=Anonymous]Learning different algorithms is fine. There's nothing wrong with learning multiple ways to solve a problem (a lot of kids love lattice multiplication, for example, but imo it's pedagogically useless). What you want is kids who notice when they are off by a power of ten or two because they have reasonable number sense. So if they multiply 16 and 21 with whatever algorithm and get 48, they know it's an error. [/quote]
