Cramming feels productive because everything is fresh for a few hours. Spaced repetition feels slower, yet it is the reason some children still remember a topic weeks later. The difference is when you review, not how long.
The schedule that works: 1 – 3 – 7 – 21
Review new material one day after learning it, then after three days, then after a week, then after three weeks. Each review is short — five to ten minutes of recalling, not re-reading.
AiDemy turns a textbook page into quiz cards, so each review round is an active recall session instead of passive highlighting.
Recall first, check second
Ask the child to say or write the answer before opening the notes. The effort of retrieving is what strengthens the memory trace; checking afterwards simply corrects it.
Keep sessions short and calm. Two focused ten-minute rounds beat one exhausted hour, especially for learners with ADHD or exam anxiety.
