Teach math and CS anyway. It's better to learn commutativity with "integer" than with "simple groups". You hand needs to know how to do the operation to get intuition to understand what the computer is showing in the screen. You can probably drop long division, like we dropped long square root a long time ago. They are nice algorithms, so it's nice to revisit them if he is interested when he is a grow up. (Even logarithm tables and slider rules are interesting, but not for everyday use.) Long sum and long multiplication are too important, don't drop them, probably only for 3x3 digits. Left the 17x16 digits cse for the computer. Approximation is super important but super hard. I've seen a few attempt to teach that to 7 y.o. kids, but I think in most cases small kids should learn exact calculation that are easier. |
