Specific Expectations
• explain how a coordinate system represents location, and plot points in the first quadrant of a Cartesian coordinate plane; 6m52
• identify, perform, and describe, through investigation using a variety of tools (e.g., grid paper, tissue paper, protractor, computer technology), rotations of 180º and clockwise and counterclockwise rotations of 90°, with the centre of rotation
inside or outside the shape; 6m53
• create and analyse designs made by reflecting, translating, and/or rotating a shape, or shapes, by 90º or 180º (Sample problem: Identify rotations of 90° or 180° that map congruent shapes, in a given design, onto each other.). 6m54
