This set of interactive PowerPoints generates a sum from the times tables every time you click within the circle. This allows you to choose a member from your class, click anywhere in the circle and a question will be revealed for that student. The PowerPoints cover:
2 & 5 Times Tables (Free in Preview!)
3 & 4 Times Tables
6 Times Table
7 Times Table
8 Times Table
9 & 10 Times Tables
11 & 12 Times Tables
There is then a 'back button' to return to the circle after each sum.
This is a great way to assess learning through questioning.
I have also used this as an extension activity with pairs of students working at the computer and testing each other.
