is this system really needed in order to grasp the concept of division? isn't saying "divide these 30 oranges to 6 boxes" enough? what does this system add to grasping the concept beyond this sentence?
actually i think the two methods of division are entirely pointless to teach youth. they are both mechanical algorithms that contribute very very little to the logical sophistication of kids, especially when you consider the other things you could teach them instead (set theory).
in other words, one method is short but easily forgotten, the other is long and remembered, but actually in real life you don't need to remember how to divide numbers and you also don't need to do it fast.

- ishener 13y agowhy not... i'm not teaching the dictionary meaning of the word, i'm teaching the concept...
- thewopr 13y agoI absolutely agree. There is a huge, amazing array of concepts that never gets touched upon because it is important that students learn to divide large numbers by hand. They were designed for an era where "computers" were people and companies hired people to keep, literally "the books" in order. That world disappeared decades ago, but this relic remains.
