Montessori. My kids’ school has kindergarteners solving trinomials [0]. My kids learned multiplication and division by 3rd grade. They’ve also memorized powers of 2 up to 2^20, but that was more me telling them about exponents one day, and then giving those as examples. However, they did learn binary trees (and binary) from their school. Kids can absolutely learn complex concepts early, they just may not be able to formally write them out until a few years later. But they’re kids, so who cares? By the time they need to be able to write out math equations, they’ll understand the underlying concepts on such a deep level that it doesn’t matter how long you make it, they’ll plow through it. I was a skeptic, and am aware that I sound like a cultist, but damn if Montessori isn’t something special. I highly recommend it. 0: https://www.montessori-theory.com/montessori-trinomial-cube/ https://www.montessori-theory.com/montessori-trinomial-cube/
