Standard Form Arithmetic
The below QuickQuestion Interface © generates 10 random questions on calculating with numbers in standard form.
Choose the maximum power for the numbers you want to generate (up to 20).
Decide which operation you would like to practice, or a selection of them.
Choose whether the powers should be positive, negative or both.
Finally, decide if you want whole numbers, or to use decimals to make it a bit more tricky.
When typing answers, an answer in standard form should be entered like "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.
