What spaced repetition is
Explain the core idea: reviewing material at increasing intervals, timed just before you're about to forget it, rather than cramming everything at once. Mention the tools students might already know (Anki, SuperMemo) and how they schedule reviews automatically.
Why it's usually used for facts
Spaced repetition was designed for discrete facts — vocabulary, dates, formulas. Note the difference between recalling a fact and applying a technique to a novel problem, which is what maths usually demands.
Adapting it for problem-solving
Describe how you adapt spaced repetition for maths: turning problem types into "cards" (e.g. "integrate by parts when you see a product of a polynomial and an exponential"), reviewing worked methods rather than just final answers, and revisiting a topic's key problem types on a schedule.
A practical starting point
Give a concrete suggestion — e.g. one card per technique, or per common mistake, reviewed weekly and then monthly as it sticks. Mention any tool or template a student could start with today.
