Grade 9 (1D)‎ > ‎

Unit 4 - Measurement & Geometry (Ch. 7 & 8)

Chapters 7 & 8 from the textbook
This fourth and final unit focuses on different methods of measurement. We begin with a discussion of angles in triangles and quadrilaterals and finish with maximizing the area and volume of figures.

Most of our unit can be found online here:  khanacademy.org/math/basic-geo/basic-geo-shapes
