Indices
The below QuickQuestion Interface © generates 10 random questions on indices.
Choose whether you want to practice the operations on indices, the simplification of negative or fractional indices, or a mixture of these.
Set a maximum power to appear in questions, and decide if you want to allow negative powers (for simplifying negative powers this option does not matter as they will all be negative).
Finally choose if you want to practice with number bases, letter bases, or mixed (such as 2a^3).
When typing answers, use the ^ symbol to represent powers, the / to denote a fraction, and if you need to do a squareroot use sqrt(9) or sqrt[3](27) for the cuberoot of 27.
Type the answer in the answer boxes, and check your answers.

Ideas for Teachers
This is a good alternative to the QQI activity, if you just want to put 10 questions on the board. Then you can get answers from students to enter in the boxes before checking them, and correcting as necessary.
However, the real power in this activity is when you get the students using it themselves. In a computer lesson, set them all going on the activity, and get them to repeat until they get every question correct.
Or you can set it as a homework, telling them the conditions to use (different conditions for different students to differentiate the homework). Then get them to do one or two sets, all correct, and to take a screen shot and either email it to you, or, even better, stick it in their books. Since the questions are random, every student will get a different set of questions, and the immediate feedback means they can go back and correct their work straight away.
