goteachmaths.co.uk Messenger! – Accurate Construction with Protractor and Compass. In this game, one student at a time acts as a ‘messenger’ for the others in their team. Without running (!), they relay information about the questions (posted around the room) to their teammates who answer them (draw the shapes). Students can mark their own work at the end. With the points system, students can attempt appropriately difficult questions.
