What Are Spaced Repetition Flashcards for Math?
Spaced repetition flashcards are a learning tool designed to combat the forgetting curve by presenting information at increasing intervals. For math, this means reviewing a formula, theorem, or problem type just before you're about to forget it. This technique moves knowledge from short-term to long-term memory efficiently. Instead of cramming, spaced repetition provides a structured, effective way to master everything from basic algebraic identities to complex calculus rules, ensuring you can recall them when needed.
