Lesson plan

1. -Seema Choudhary DAV Cent Public School,Malerkotla

2. Pre Requisite Knowledge Basic knowledge of plane like circle triangle and quadrilateral Properties of circle and cyclic quadrilateral Teaching Aids Black Board, Chalk, Duster, Charts. Methodology Deduction method, Demonstration and Learning by doing Types of Assessment Assignment sheet will be given as homework at the end of topic. Separate sheets which will include questions of logical thinking and higher order thinking skills will be given to the above average students. LESSON PLAN TOPIC: Area Related to Circles

3. Learning Objectives Introduction and definitions related to the circle, radius ,diameter ,chord , segment, sector, circumference etc. Circumference and perimeter of the circle, semi circle, quadrant and length of arc. Area of circle, minor-sector, major-sector, minor-segment, major-segment etc. In calculating area of segment of a circle, problems should be restricted to central angle of 60 o ,90 o ,120 o . Area related to the other plane figures like triangles and quadrilaterals should be taken. Problems based on the combinations of plane figures: circle, triangle and quadrilateral should taken and discussed thoroughly.

4. Procedure Start the session by checking the previous knowledge of the students, by asking the questions about radius, diameter, chord, segment, sector etc. After this introduce this topic area related to the circle(plane figures) step by step as follows. 1.Introduction Circle, triangle, quadrilateral and other polygons are two dimensional figures. So these figures are called plane figures. In this chapter we will discuss the area related the plane figures and combination of plane figures. First of all, teacher will define all the terms which are related with the circle, like definitions of circle, centre of the circle, radius, diameter, chord, segment, sector, minor segment, major segment,minor sector,5 major sector, semicircle, quadrant and circumference of circle.

5. 2.Circumference and perimeter Now teacher will explain different properties of circle to the students and explain the difference between the circumference and perimeter of the circle. Length of curved surface is called circumference and length of the boundary is called perimeter both are same.But in semi-circle both are different. 3 .Now teacher will explain the formula and method of finding the circumference and perimeter of the circle, semi-circle and quadrant. Circumference of semi circle= Perimeter of semi-circle= +2r Perimeter of quadrant of circle=  

6. 4.Area of Segment and Sector Now teacher will explain the formula and method of finding the area of the circle, semi-circle, minor segment, major segment, minor sector, major sector all with central angle angle 60 o ,90 o ,120 o Also help the students in the implementation of these formulas. Area of circle= Area of minor sector= Area of major sector= Area of quadrant=  

7. 5.Now explain the area related to different types of triangles and their implementations in different problems. Area of triangle, right angled triangle, equilateral triangle and scalene triangle. Area of triangle= base X height Area of equilateral triangle= 6. Angle made by minute and hour hand of the watch. Here we will explain the angle made by minute hand in one minute=6 o and angle made by hour hand in one minute= We will also explain the topic by taking some examples  

8. Learning Outcomes After studing this topic students will know The circle and its components. The area and perimeter related to all the plane figures like circle,semi circle, quadrant, segment, sector, different types of triangles and different types of quadrilaterals. Student Deliverables Review questions given by the teacher. Students can prepare presentation on the formulas related to the plane figures. Solve N.C.E.R.T problems.
