    One of the best ways to motivate little kids to learn math (n = 2 admittedly) is to present it as secrets for cheating.

        I just showed my 5 yo how if you know 4^2 = 16, you can say how many balls are in a 4 x 4 square without counting them all.

        When he actually counted them and found that he was right, there were 16, he was delighted.

        Cheating? Or shortcuts? The implication of cheating would not sit well with a lot of kids given what they are otherwise told.

        I find kids (n = 2 again) tend to be very amused by the thought of doing something secret and forbidden. Especially if no one gets hurt.

        Ah, not questioning that - it’s all I can do with the current math approach to not just say “Stop, let’s do it Dad’s way…” Wording question.

        YMMV but for me it was "tremendous instrumental utility in min/maxing in video games and paper RPGs."

        Among the most important research papers I ever solicited peer review on was titled "SRMs or Large Pulse Lasers first?"

        Although I didn't know it, I had accidentally reinvented Monte Carlo sampling, by hand since I didn't own a computer at the time.

        (Incidentally, Large Pulse Lasers first. Science says so. The mechanism is they strip the armor and then your SRMs rack up more crits.)

        That might have unintended negative long-term consequences.

        Math skills blossom when they realize that's how you count money for candy/toys, etc.

        Also try @KumonUK. Think of it as real world training of kids brains a'la AI instead of rote. It makes arithmetic so easy for kids.

        It scales with age too. I remember in calc being amazed that I could write a for loop to do integration *for me*. No more stupid tables.
