Choose 3 Numbers
This starter creates 3 random numbers, and adds them in pairs. The idea is that you reveal the totals and students have to work out the original numbers.
Choose which operation you want to use, and the range of values. Press New Question to generate the numbers, and then click the relevant boxes to reveal different numbers.
This activity was invented by Mike Ollerton and is the second Probing Questions set by Mr Barton.
