Standard Form Conversions
The below QuickQuestion Interface © generates 10 random questions on converting between normal numbers and numbers given in standard form.
Choose the maximum power for the numbers you want to generate (up to 20).
Decide on which way you wish to convert, or choose Non-Standard 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".

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.
