Welcome to the Sched site for the Northwest Mathematics Conference!

ALL WORKSHOPS ARE FIRST COME, FIRST SERVED - signing up in Sched does not guarantee you a spot in a session. However, planning your day in Sched really helps us anticipate any potential need to make room changes.

If you create a free account, you can plan and edit your schedule. You may wish to select more than one session in a timeslot as a backup, in case your first choice of session is full.

On the right side of the schedule you can filter by grade band. This will include the sessions which span more than one grade band. You may also wish to view the Schedule as Expanded.

Trigonometry with More Confidence and Intuition: Beginning with Coordinates on the Unit Circle
Friday October 25, 2024 10:05am - 11:20am PDT
Alpine E, Westin
Trigonometry instruction typically begins by defining sine, cosine, and tangent as ratios. In this session, I share an alternative approach in which sine and cosine are introduced as coordinates on the unit circle, with tangent as an associated slope. This method enhances understanding, rapidly leading students to an intuitive grasp of trigonometric concepts.
I will share how students use this strategy to easily estimate the sine, cosine, or tangent of any angle and from there go on to derive various properties. I hope this leaves you with a new perspective on developing trigonometry with your students.
