http://illuminations.nctm.org/LessonDetail.aspx?ID=L469
A lesson plan for grade 9 Mathematics
The final lesson of a four part series offers students the opportunity to think about the ideas they have discovered in i-Math as a whole.
Students will:
- Use various representations to help understand the effects of simple transformations and their compositions.
- Understand and represent translations, reflections, rotations, and dilations of objects in the plane by using sketches, coordinates, vectors, function notation, and matrices.
- Draw and construct representations of two- and three-dimensional geometric objects using a variety of tools.
