How a lesson works

Four steps, the same every time.

  1. 1ReadShort sections with pictures. Tap any underlined word for its meaning.
  2. 2WatchOllie writes and draws the idea on a whiteboard, step by step.
  3. 3PlayA hands-on game or lab. Get it wrong, and Ollie shows you why.
  4. 4QuizA short Lesson quiz with instant feedback, then your summary.

Every lesson on OHM works like this.

With an account, a short check finds the right starting point, each lesson adapts to how it went, Ollie answers any question, and parents see the progress.
