I’m starting my each of my final 21 lessons with a slide from this. The “recall” section has the same 15 topics that repeat themselves every 3rd lesson. The questions are all from the same 15 or so topics, so students gain familiarity with them. The topics are ones my class need extra practise on or just need constant reminders on!

Click on the timer on the top left and it takes 8 minutes to fade away. When you click on an blue question box it disappears to reveal the answer* (*can’t guarantee error free!)
