Ten questions regarding volume of rectangular prisms are presented to your geometers, most of them requiring the multiplication of length, width, and height. The assignment is acutally an interactive resource in that learners answer mutliple choice questions on the computer. They can click a link at the bottom of the page to see the correct answers, but then their choices are no longer visible. Consider projecting the quiz on the white board, having takers write their answers down on a piece of paper, and then displaying answers to have them self-evaluate.
