this is because the rule for eleven is the simplest, and each subsequent rule is only a bit different from its predecessor: for example the rule for multiplying by six is very similar to the rule for multiplying by twelve and so on. If you tried to learn the rule for multiplying by three before learning all the others you would get lost. Frankly I think some of the later, more complicated rules are a bit self-defeating.
