About This Lesson
You project the grid onto the board and pick 2 students to stand; one on each side. You ask a question (e.g. a coordinate on the line y=2x) and the first student to ‘slap’ the answer is awarded a point – the first to three points stays at the board and a fresh challenger is picked. Once students have got the hang of the type of question you can go round the room with students asking the questions.
