Students learn how to perform reflections on a grid using straight line graphs as the mirror line. As learning progresses they are challenged to describe reflections by stating the equation of the mirror line.
Differentiated Learning Objectives
- All students should be able to reflect an object on a Cartesian grid using a vertical or horizontal linear function as the mirror line.
- Most students should be able to reflect an object on a Cartesian grid using a mirror line in the form y=mx+c.
- Some students should be able to perform and describe a reflection on a Cartesian grid.
