Expanding Quadratic Brackets
The below QuickQuestion Interface © generates random questions on expanding quadratic brackets.
Choose which types of expressions you would like to expand, or choose one of the random options to get a mixture of questions.
Choose if you would like to include negatives in the expressions and whether to use a random letter.
When typing your answers, use ^ to represent a power (for example "x^2 + 5x + 6").
Use the buttons to create random questions and show the answers.
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).
