Re: Education
The thing about 12s is actually the opposite. It's the primes that we need most. Knowing 12s can be replicated by knowing 6s and how to double. Or 3s. Which also ensures that the kids ( and adults) understand what they are doing with these tables. Ironically rote learning of the tables makes understanding, manipulating and applying them less likely. Better that the kids realise that if they do want to multiply by 12 they can multiply by 3 then 4.
