Indices
The below QQI Relay © shows one question at a time, and to proceed to the next question, you need to answer the current one correctly. Decide how many questions you want (you can always finish early if need be).
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.
When the questions appear, type your answer in the boxand click Check Answer to see if you are right. If correct, move on to the next question.

Ideas for Teachers
This activity requires each pupil to have access to a computer or other internet enabled device. They will each get a different random set of questions, and at the end you can see how they did in the results table. This is great for spicing up an activity as it adds an element of competition to the work.
Get them to set a high number of questions, such as 100, and then get students to answer as many as possible in 5 or 10 minutes. Have a prize for the one with the highest point score (awarding accuracy and speed).
