Standard Form Conversions
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 the maximum power for the numbers you want to generate (up to 20).
Decide on which way you wish to convert, or choose NonStandard to get examples where they are multiplied by a power of 10, but not in standard form. For a mixture of types, choose Random.
Finally, choose whether the powers should be positive, negative or both.
When typing answers, if giving an answer in standard form enter it in the form "1.3436x10^3".
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).
