Lesson Plan : Learning Trigonometry
Teacher Name: | Ronnie P Thomas |
Grade: | Grade 9-10 |
Subject: | Math |
Topic: | Learning the basics of Trigonometry |
Content: | Learning the basics(sin,cos,tan) using triangles, unit circle. Also learning some basic formulas. Try out some problems. |
Goals: | Students will be able to understand and solve problems requiring basic trigonometry. |
Objectives: | Define sin,cos and tan based on a right angled triangle. Know the values of sin,cos for few angles. Use basic formulas to solve problems. |
Materials: | Unit circles, sin,cos,tan graphs, right angled triangles showing the trig. identities. |
Introduction: | Start with the triangle. Define sin and cos for starts. Then continue with tan. |
Development: | Demonstrate the unit circle, show the graphs depicting the sin,cos,tan curves. Also explain the basic formulas. |
Practice: | Find sin,cos,tan values of a triangle. Use the trig. identities in a formula. Remember the basic sin,cos,tan values for common angles. |
Accommodations: | Provide formula sheets for people having trouble understanding the concepts |
Checking For Understanding: | Practice problems. Being able to explain trig. identities using the unit circle and right triangles |
Closure: | |
Evaluation: | Final test at the end of the course. Slightly tricky problems. |
