Beginner lesson

Your mind holds only a few loose items at once. Grouping them into chunks lets you hold more.

  1. Look at the full list once.
  2. Group into chunks of 2–3.
  3. Say the chunks quietly with rhythm.
  4. Recall chunk by chunk.
Worked example: 9 4 1 7 2 6 → '941 – 726'. Two chunks are easier than six digits.
