What you are saying makes perfect sense in the context of language learning. I also found spaced repetition, Anki etc to be extremely effective for that purpose. My point here is rather that this approach will not work with mathematics, simply because unlike language learning, which is mostly about acquiring and memorizing large amounts of simple X to Y mapping, mathematics has much less to do with memorization and more to do with building mental framework and placing new knowledge in appropriate places with in.
