January 3-13, 2012 - Lectures on the following:
o Angles, Measurement of Angles
o Trigonometric functions ,applications of trigonometric functions
** Written assessment ( 2 Long tests ) = 20% of Midterm grade.
January 16, 2012 - Discussion on what and how to make the final/group output.
January 18, 2012 – Selection of possible structures/scenarios inside or outside of USLS campus.
Janurary 30 – February 3 , 2012– Presentation of Final Products
Day 1 – Presentation of Final Products of groups 1 – 4
Day 2 – Presentation of Final Products of groups 5 – 8
Day 3 – Presentation of Final Products of groups 9 -11
BIG IDEA: TRIGONOMETRY....A USEFUL TOOL
ESSENTIAL QUESTION: What are the real-world applications of right triangles?
TOPICS TO BE COVERED:
o RIGHT TRIANGLE- BASED DEFINITION OF TRIGONOMETRIC FUNCTIONS
o PYTHAGOREAN THEOREM
o ANGLE OF ELEVATION
o ANGLE OF DEPRESSION
EXPECTED FINAL PRODUCT : Power point presentation or video presentation
Each group are expected to perform the following activities:
1. Know and understand the following concepts :
o RIGHT TRIANGLE- BASED DEFINITION OF TRIGONOMETRIC FUNCTIONS
o PYTHAGOREAN THEOREM
o ANGLE OF ELEVATION
o ANGLE OF DEPRESSION
2. Discuss with the group to come up with least 3 structures/scenarios anywhere in Bacolod City.
3. Data gathering. Take snapshots, or video of the structures the group have chosen.
4. Analyze the parts of the structures and determine the length, height, angle of elevation/depression in which
the trigonometric functions can possibly be used.
5. Reflect on environmental issues and suggest realistic and practical solutions relevant to the
structures/scenarios chosen.
6. Create a power point presentation or video presentation. Power point presentation/video presentation
should discuss the following:
o Short discussion of the topics stated above.
o Structures/Scenarios chosen.
o Computation of a specific part (height, length, or angle)
o Importance of the structures in the environment/area/community.
o Conclusion and Recommendations

2. o Reflection (What values have you learned in making the FINAL PRODUCT ?)

1. Written Tests – 20 %
2. Oral Presentation – 10 %
3. Content of the Presentation – 30%
4. Technical Aspect of Final Product – 10 %
5. Conclusion and Recommendations – 20%
