SUBJECT: MATHEMATICS
CLASS: X SECTION: (A+B)
SYLLABUS TO BE COVERED FROM: 16/11/2015 TO 30/11/2015
TOPIC: Height and Distances (Application of Trigonometry)
CONTENT: The aim of the topic is to develop
the fallowing concept about the Trigonometry.
· Introduction of trigonometry based on
the concept learnt in the previous year
and bridging the gap if necessary
· Geometrical interpretation of
trigonometric ratios
· Etymology of Trigonometry.
· Linking the concept of trigonometry and
geometry to discover values of multiple angles
· Concept of Height and distance with
special reference to the Pythagoras
triangle and height as perpendicular where as base as distance.
· Drawing the figure and transfer the
data of the word problem into a known Pythagorean triangle, location of angle
and its corresponding sides.
INSTRUCTIONAL OBJECTIVES: pupils will
be made to know about
· New terms found in the topic.
· To read the problem, analyze
critically and transform the data as right angled triangle then find the
solution to the given words problem.
· To develop the skill of transforming
the given statement into right angled triangle hence apply the concept of
trigonometry to solve the day to day life problems as and when they come across
.
· Definition of angle of elevation, and
angle of depression,
· To develop the skill of identifying
reference angle, object and its angle of elevation/angle of depression.
TEACHING AIDS TO BE USED:
To reinforce
the concept for ever in the pupil’s mind the fallowing teaching aids can used.
· A chart of right angled triangle,
highlighting such as Base, opposite side and Hypotenuse to reinforce the
concept for ever among young children.
· Interpret the concept of angle of
elevation Geometrically and analyze the data with statement hence find the
solution to the given problem
· Interpret the concept of angle of
Depression Geometrically and analyze the
data with statement, hence find the solution to the given problem
· Power point presentation to be shown in smart
room.
INNOVATIVE PRACTICE TO BE USED
Pupils will be divided into sub
groups of four members in each group and question on each concepts learnt in
the above topic has to be supplied after the completion of topic instructed the
pupils to solve by discussion and to come out with solution.
LABORATORY ACTIVITY TO BE CONDUCTED
Each
four members group of pupil were instructed to discuss the problem assigned and
perform the activity to get more enthusiasm in teaching learning process for
ever.
· To
find the height of a building/water tank/tower /electric pole /top of
the tall tree, using clinometer
· To
list out figures of day to day
life situation based on the concept of angle elevation identify the
reference angle , opposite side and
base,
· To list out every day examples to be
used for angle of elevation /depression.
·
PROJECT TO BE INITIATED
1) To study the distance between
different of a geometrical figures when it is displaced/rotated. Enhance the
familiarity with coordinate geometry.
2) Representation of Golden quadrilateral
plan of action from India map and its
location in coordinate axis and hence study the cost of expenditure for
construction of Golden quadrilateral connecting the important cities of India
(cross curricular project linking the concept of literature , English, Social
science, science Mathematics. And special reference to the Mines, and minerals
available around the Golden quadrilateral,)
3) Each group of pupils will directed to
prepare power point presentation on the topic Coordinate Geometry and its use
in day to day life situation.
ASSIGNMENT/HOME
WORK TO BE GIVEN
To
have thorough understanding of knowledge about the topic and supplement the
concept learnt in the class room the fallowing methods can be adopted.
· Problems assigned by the teacher
· Problems other than text book.
· Problems collected from reference book
· Problems asked in CBSE sample papers
EXPECTED
BEHAVIORAL OUTCOME OF THE TOPIC
