Trigonometry
Overview
Analyze situations, check for limitations, and examine appropriate methods of solutions using trigonometry practice.
Manipulate trigonometric functions and substitute equivalent expressions.
Work in small groups encouraging classmates and communicating thoughts.
Maths
Step 1. The teacher shows the model of a right angle triangle and stands near a vertex naming it as Θ. Students are asked to name the relative adjacent and opposite sides. Same process is repeated by flipping the vertex. Student identifies the relation between the sides and Θ. Thus confirm that when Θ changes adjacent and opposite sides will change. step 2. Slide 2- Pythagoras theorem is introduced. step 3. slide 3- Similarity is introduced. Test of Similarity is revised. Activity: Dividing the class of 40 students in 5 groups. Providing flash cards which asks the students to identify if triangles are similar and name the test of similarity. Step 4. slide 4, 5, 6 more examples are studied. step 4: Slide 7, 8: Names of trignometric ratios are introduced. Step 5. Slide 9,10: A story is narrated to students with voice modulation, so that they remember the trignometric ratios for ever. Step 6: Slide 11 to 14: Daily life examples of trigonometry are shown to students Step 7: Closing: Evaluatiom: Activity: Dividing the class of 40 students in 5 groups. Providing flash cards along with answer sheets. Each group gets two triangles where the student has to write down all trignometic ratios using the sides of the given triangles. This will help teacher identify if the topic is understood by each student.
