Enrolling Now for 2026-27 School Year.
Dear Learning Coach,
Thank you for partnering with CCA and investing in your learner’s education. This Learning Coach Guide is intended to help you support your learner in their Geometry course.
Within this guide, you will find the goals, components, and features of the online course. Please take time to read and review this information so you understand how to help your learner interact with all the course’s elements.
The Learning Coach Guide also includes information about each of the units in this course. On each page of unit information, you will discover the following.
CCA wishes you and your learner a terrific school year!
Your role as a Learning Coach is very important. Here are a few ways you can help your learner do their very best in the course.

Course Information
Part B
Course Information
This Geometry course is a comprehensive study of geometric concepts, including the basic elements of geometry, proofs, parallel and perpendicular lines, rigid transformations, triangles, similarity, congruence, trigonometry, quadrilaterals, circles, area, and 3D figures. In addition to the topics, students will:
Within the course, there are different components your learner will interact with. These components will not be used every day.
Lesson Bundling
A lesson bundle is a collection of lessons that stack up to equal one full class period. On some days, learners will see bundles, such as a Knowledge Check and the daily lesson or the combination of a Quiz Review and Quiz.
In Geometry, learners will see a specific bundle of lessons within one day.
Lesson Components
Each lesson has its own components to help guide your learner through the lesson.
Assessment Formats
The course includes assignments and projects. These graded assignments allow your learner to show what they have learned and apply their new skills. All CCA assignments and projects include these components.
In addition to assignments and projects, this course also includes quizzes and tests.
Unit Overview
Your learner will explore the basic terms that are used in geometry, and how to use them with physical and digital tools.
This unit also introduces the topic of geometric proof. A proof is arranged to prove statements about a problem, but it is also to help your learner build their understanding of how and why they arrive at an answer.
