### How does a "Multi-Day" course work?

Meets multiple times at scheduled times

Live video chats, recorded and monitored for safety and quality

## Description

### Class Experience

Learners will develop further familiarity with trig identities, including proving them using known angles. Learners will become familiar with key trig identities: sum and difference, double-angle, half-angle, reduction, and sum-product conversion Learners will solve trigonometric equations. Learners will use the laws of sines and cosines. Learners will work with vectors.

Learners will have practice problems to work in Rover for each lesson. Other assignments, quizzes, and tests will be in TeacherMade. Occasionally, such as in advance to clear group time for interactive tasks or when lecture topics take longer than anticipated, learners will be assigned video tutorials to watch outside class time.

Scratch paper and pencils, or a whiteboard and markers. Learners who are preparing for college admissions are advised to keep a portfolio (digital or on paper) of major assignments and 2-3 different types of problems, fully worked, per routine practice assignment; the materials of the student's choice should be available for this from the beginning of class. Examples include a Google Drive or Dropbox folder, LibreOffice software (Writer and Math), a binder and hole-punched printer paper or a hole puncher, etc. Consider that if you are applying to multiple colleges, a digital portfolio is easier to duplicate, and can be printed out if a physical copy is wanted. For this class, learners can use GeoGebra exclusively as their graphing calculator, but students whose intent is to take a credit-bearing exam should begin practicing with a calculator approved for that exam as soon as possible.

In addition to the Outschool classroom, this class uses:

Learners will receive numerical grades for practice and for each major assignment in a written report at the end of the class, and a current draft of their grades so far upon request during the class.

1 hour 40 minutes per week in class, and an estimated 2 - 4 hours per week outside of class.

TeacherMade is a site designed for school use which allows learners to access and complete worksheets, tutorials, and practice problems. If they wish, such as for added privacy, learners can sign in using a nickname or pseudonym. Rover is an automatic-scored practice site based on the OpenStax precalculus-level textbooks. Learners will need to set up accounts; costs will be covered as part of their tuition for the class. GeoGebra is a free, open-source math calculator, graphing calculator, and dynamic geometry site. Learners do not need an account to use it. Explain Everything is a shared whiteboard, similar to Google Jamboard but more flexible. Learners do not need an account and can access the board to write on it through a link. Learners who do not specifically want to write on the board don’t need to access Explain Everything at all – I will share the screen in Zoom and they can watch.
