Thanks to Kal for sharing this tip.
I saw a great activity when observing a trainee teacher yesterday. The activity is to do with recall of prior topics.
As a start activity or “Do It Now” three questions are put on the board as pupils enter:
The FISH question requires pupils to recall something that they were doing last lesson.
The DOG question requires pupils to recall something that they were doing one-two week ago (previous topic).
The WHALE question requires pupils to recall something they were doing a month ago (perhaps two topics ago).
This is a simple method of introducing spaced learning into lessons. Going forward a department could incorporate specific questions into a scheme of work.
