Probing questions
What percentages can you easily work out in your head? Talk me through a couple of examples.
When calculating percentages of quantities, what percentage do you usually start from?
How do you use this percentage to work out others?
To calculate 10% of a quantity, you divide it by 10. So to find 20%, you must divide by 20. What is wrong with this statement?
On a 1-100 grid, 50% of the numbers are even. How would you check?
Give me a question with the answer 20%.
