Compound Interest and Simple Interest
The below QuickQuestion Interface © generates random questions on compound and simple interest.
Choose which types of percentages you would like to deal with (Non-Calculator percentages are 1%, 5%, 10%, 20%, 25%, 50%, 75%).
Decide whether you want your values to increase, decrease or have a mixture of both.
Pick which type of interest you would like to apply (Simple, Compound or a Random selection) and what the maximum term of the investment should be.
Finally, choose the currency suitable for your location.
When entering answers, remember to include the currency symbol, and that money is given to 2 decimal places.
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 mini-whiteboards. 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).
