Unit 5: Geometry

Students will grow their skills of visual perceptibility by exploring the world of visual mathematics,  2-D and 3-D shapes, the coordinate plane, surface area, volume, transformations and congruence.  Students, having mastered the Discovery Method process, are able to apply it in this unit in its full power.
