Percentage Change
The below QuickQuestion Interface © generates random questions on finding the percentage change (or profit and loss) between two numbers.
Choose which types of percentages you would like to deal with.
Decide on having increasing amounts, decreasing amounts, or a mixture of both with Random.
Decide if you want the problems to be profit/loss questions.
When typing answers, give them to 1 d.p. and remember to include the % sign.
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).
