Trigonometry Lesson Plans

Students explore the concept of trigonometry. In this trigonometry lesson, students research real world scenarios that require trigonometry. Students make a presentation of the real world scenario they found and how the scenario uses trigonometry.

Students relate trigonometry to the real world. In this trig lesson, students investigate a variety of real world application using vectors, time, distance, and trig functions. They solve equations based on the unit circle and trig values.

Learners experience real life situations where trigonometry is used on a daily basis. They utilize trigonometry to the solving of application problems that involve the calculating of the sine, cosine, and tangents of a given angle as well as the finding of the length of a missing side of a right triangle given an angle and a side.

Students explore mathematics by analyzing images. In this trigonometry lesson, students discuss ways to utilize trigonometry formulas to measure everyday objects such as childhood toys. Students share their measurements with their classmates through a presentation.

Students investigate the different properties of trigonometry. For this precalculus lesson, students find the six different identities of trigonometric ratios. They relate the ratios to that of a right triangle and apply it to real life scenarios.

Students take an Algebra II/Trigonometry sample test.  In this Algebra II/Trigonometry sample sample test instructional activity, students take a sample test for Algebra 2/Trigonometry.  Students solve 39 multiple choice/short answer questions about topics including radicals, equations of circles, exponential equations, angle measures, etc.

Students identify the different ratios of a right triangle. In this trigonometry lesson plan, students calculate the sine, cosine and tangent of a right triangle. They differentiate between right and oblique triangles.

Twelfth graders test their knowledge of Algebra II and Trigonometry.  In this Algebra II/Trigonometry lesson, 12th graders are provided with a copy of an Algebra II/Trigonometry Regent Exam from the fall of 2009.  The exam has questions in multiple choice and open ended format and includes the answer key. 

Students complete measurement math problems regarding building a tipi and then create models of tipis on their own. For this tipis lesson plan, students use geometry and trigonometry to construct their tipis.

Students memorize trigonometry vocabulary and complete several homework assignments.  In this trigonometry lesson students view a video independently on trigonometry functions. and download and complete 3 worksheets
