M205:TrigonometricFunctions
Why do some real-world phenomena produce graphs shaped like waves? How can trigonometric functions model the rising and falling of ocean tides each day? Using radian measure, mathematicians have been able to define an intriguing family of functions with unique properties that help us model cyclical phenomena across science and nature.
In M205 Trigonometric Functions, you will:
• Explore the unit circle and develop an understanding of how radians are defined
• Investigate the properties of trigonometric functions and how their graphs behave, using graphing technology to aid analysis
• Apply trigonometric functions to model real-world situations involving periodic patterns
Examples of careers that use M205 concepts: sciences, engineering, oceanography, and gaming.

Assessments
Introduction to Badge Assessments
This document provides an overview of the different badging forms of assessment.
Pre-/Post-Task
These tasks should be administered before instruction begins on a new badge and again as badge instruction comes to a close. The pre-task gives students an opportunity to see where their learning is headed, identify any relevant background knowledge or skills they already possess, and establish a starting point for the badge. The post-task provides an opportunity for students to demonstrate what they have learned and compare their new thinking to their original responses. Together, these tasks help students recognize their growth over time while providing teachers with meaningful information to guide instruction and support learning.
Portfolio Resources
A portfolio of evidence consists of student-produced artifacts that demonstrate proficiency against a badge’s CPEs. The portfolio development process involves students selecting and reflecting on artifacts that showcase their understanding of badge CPEs, followed by iterative teacher review and student-teacher conferencing until the work demonstrates proficiency.
