Understanding coordinates in all four quadrants. Using coordinates to construct squares, rectangles, triangles, parallelograms, rhombuses and midpoints. All these activities require the student to drag points to required positions and observe the resultant coordinates.

Using coordinates in all four quadrants. Symmetries based on reflections (in the axes and in the lines y=x and y=-x) and rotations (half and quarter turns). All these activities require the student to drag points to required positions and observe the resultant coordinates.

Using coordinates in all four quadrants. Patterns of coordinates that all lie on a given line or curve. All these activities require the student to drag points to required positions and observe the resultant coordinates.
