Expanding Single Brackets
The below QuickQuestion Interface © generates 10 questions on expanding single brackets and simplifying the resulting expressions if necessary.
Choose which type of brackets you would like to practice, or choose random for a mixture of the different difficulties.
Decide if you only want a single bracket to expand, or two brackets with the resulting expression needing to be simplified.
Finally, choose if you want to include negatives in your brackets.
When typing answers, the order is important. Pairs of letters should be entered in the order they appear (outside bracket first). When simplifying, again, the final answer needs to be in the correct order as given in the question.
For example, 3a(2a+4b)+2a(2a+5) = 10a^2+12ab+10a.

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.
