- slides

- Duration
- about 5 minutes
How to use it
- Give younger classes more time per question, so slower students have a chance too.
- After each reveal, ask someone how they worked it out. The methods are often more interesting than the answer.
- Swap the questions for your current topic now and then; it takes two minutes in the editor.
The answers in the preview are examples. In your presentation, every slide starts empty.
