Increase and Decrease by a Percentage
The below QuickQuestion Interface © generates 10 random questions on increasing or decreasing a value by a percentage.
Choose which types of percentages you would like to deal with (Non-Calculator percentages are 1%, 5%, 10%, 20%, 25%, 50%, 75%).
Decide on if you want to have questions involving increasing by a percentage or decreasing, or choose Random to get a mixture of both.
Finally decide if you want the calculate the actual final amount, or just to find the multiplier needed to do the calculation.
When typing answers, give them to 3 d.p.

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.
