Lesson Planning of Geometry (Recognize point, Line segment, ray)
Subject Mathematics
Grade 3^{rd}
Students` learning outcomes
 Recognize point, line segment, and ray
Information for Teachers
 In Geometry the point is a fine dot that represents a definite position or location.
 The line which joins two points is called line segment.
 If we extend a line segment from one end in a particular direction, it is called a ray.
 While teaching the lesson, the teacher should also consult textbook at all steps wherein and whenever it is applicable.
Material / Resources
Writing board, chalk/marker, duster, torch / toy laser light, pencil, sharpener, sheets of paper
Introduction
 Ask the students to sharpen their lead pencils and mark a dot by the sharp tip of their lead pencils on the notebooks. Tell them that this dot is called point.
 Ask them to mark one more point on the paper and ask how they will distinguish these two points.
 After collecting responses, tell them that to distinguish different points, we give them names using capitals letters, such as A, B, C. these points are read as point A, point B, point C.
Development
Teaching Approach
Demonstration method, Assignment method
 Let`s do some activities
Activity 1

Activity 2

Activity 3

Activity 4

 .Ask the students how many end points a ray has? (Expected answer would be as; One)
 A is the end point of this ray, because it I the starting point B in the point through which we can extend this ray, so it is not an end point.
 Ask the students to draw these rays on their notebooks and name them.
 Tell the students that we can`t measure the length of a ray, because it has only one end and we can’t write
Activity 5

Conclusion / Sum up
 In Geometry the point is a fine dot that represents a definite position or location.
 The straight line which joins two points is called line segment.
 If we extend a line segment endlessly from one end in a particular direction, it is called a ray.
Assessment
 Draw line segments XY and EF
 Draw rays AB and EF
 Teacher is required to involve the students in solving the problems given in the exercise at the end of unit/chapter.
