Overview
The sample material
provided here is the "Looking Back" Lesson for this unit. (Alignment
of CorePlus Mathematics with the Common Core State Standards)
Instructional
Design
Throughout the curriculum,
interesting problem contexts serve as the foundation for instruction.
As lessons unfold around these problem situations, classroom instruction
tends to follow a fourphase cycle of classroom activities—Launch,
Explore, Share and Summarize, and Apply.
This instructional model is elaborated under Instructional
Design.

How the
Geometry and Trigonometry Strand Continues
In Course 4:
Preparation for Calculus, geometry and algebra become increasingly intertwined.
Students develop understanding of twodimensional vectors and their application
and the use of parametric equations in modeling linear, circular, and
other nonlinear motion. In addition, students intending to pursue programs
in the mathematical, physical, and biological sciences, or engineering
extend their ability to visualize and represent threedimensional surfaces
using contours, cross sections, and reliefs; and to visualize and sketch
surfaces and conic sections defined by algebraic equations. They also
extend their understanding of, and ability to reason with, trigonometric
functions to prove or disprove trigonometric identities and to solve
trigonometric equations. They also geometrically represent complex numbers
and apply complex number operations to find powers and roots of complex
numbers expressed in trigonometric form. (See the CPMP
Courses 14 descriptions.)
