Collecting Like Terms
The below QuickQuestion Interface © generates random questions on collecting like terms.
Choose how many variables you would like to appear in the questions.
Decide on the maximum number of the coefficients.
Pick how many terms you want in the unsimplified expression.
Choose whether or not to allow negatives, and finally if some of the terms can be constants.
When entering your answers, the order of the terms does not matter.
There is a 10QQI version of this activity which generates 10 random questions at a time.

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).
