Percentages of Amounts
The below QuickQuestion Interface © generates random questions on finding the percentage of an amount.
Choose what type of percentages you want to be dealing with in the questions. Noncalculator percentages (1%,5%,10%,20%,25%,50%,75%) should be calculable without a calculator easily. The other options include whole number or decimal percentages and whether they are above or below 100%.
There is a 10QQI version of this activity.

Ideas for Teachers
The QQI activities are a great way to get all students working. Put random questions on the board, and then get students to answer them on miniwhiteboards. Once all students have answered, and held up their solutions (with working), reveal the answer to see if they were right. Discuss any misconceptions from the working they have shown, or if they have all got it correct, move on to another question (changing the options to make if more difficult if necessary).
