What will students		In this unit, students develop their understanding of the cartesian coordinate grid and solve problems in all four quadrants. Students will be familiar with coordinates from work at primary school and in other subjects. The tasks in this unit will give students opportunities to apply their understanding from previous units including negative numbers and geometric properties of triangles and quadrilaterals. The unit begins by revisiting their understanding of working with a number line in one dimension to working in two dimensions. Students solve problems involving midpoints and develop strategies for solving related problems. Students will begin to describe the equations of horizontal and vertical lines by recognising the constant x or y coordinates along them.
