  2. Times after midday keep counting on from 12
  3. On the 24 hour clock the hours start at 0 and end at 23

  • Am - The hours between midnight and midday.

  • Pm - The hours between midday and midnight.

Common misconception

Part of the lesson requires pupils to decide whether times are before midday, at midday or after midday. Pupils can find categorising 12:00 and 00:00 tricky.

Explicit teaching points are made based around this in the slide deck. However, it is worth really focusing on these points as they come up and, when assessing the pupils during the Practice tasks, paying particular attention to those times.

As adults, there is probably no calculation involved when expressing a 12 hour digital time in its 24 hour form, and vice-versa. It is automatic, because it is embedded. To aid with this automaticity process, use flashcards outside of the Maths lesson to provide quickfire instant recall practice.
