LESSON PLAN FOR ADDITIONAL MATHEMATICS FORM 4

Subject

:

Additional Mathematics Form Four  

Form

:

4

Time

:

(80 minutes)

Topic

:

Angles of le!ation and "epression

Subtopic

:

#0$#) understand and use the concept of angle of ele!ation and angle of depression to sol!e problems

%earning &utcomes

:

Student 'ill be taught to:

i)

dentif a) The hori*ontal line  b) The angle of ele!ation c) The angle of depression for a particular situation

ii)

represent a particular situation in!ol!ing : a) the angle of ele!ation  b) the angle of depression using diagram

iii)

%earning &bjecti!es :

sol!e problems in!ol!ing the angle of ele!ation and the angle of depression

At the end of the lessons+ students 'ill be able to:

•

,nderstand and use the concept of angle of ele!ation and angle of depression to sol!e problems

•

appl sine+ cosine and tangent ratios to find angles of ele!ation and depression$

•

 measure lengths and use measurements to determine angle measures
