Lesson Planning of Parallel and NonParallel Lines
Subject Mathematics
Grade 4^{th}
Students` Learning Outcomes
 Recognize parallel and nonparallel lines.
 Draw a parallel line to a given straight line using setsquare.
 Draw a line which passes through a given point and is parallel to a given line
Information for Teachers
 Lines that lie in the same plane and don`t meet one another are said to be parallel lines.
 During this lesson teacher should consult textbook wherein and whenever it is required.
Material / Resources
Writing board, chalk/marker, duster, straws, pebbles, geometry box, textbook
Introduction
 Recall the concept of line and tell that there are some lines which never meet and never touch each other. They are called parallel lines. When curiosity rose present the following:
 Take two straws and place them in position to show straight parallel lines.
 Take some pebbles and arrange them on floor/table in curvy parallel lines and finally draw similar figures on board and tell that parallel lines never meet or cut each other.
 Draw a pair of parallel lines in the middle of the board and invite students to come and extend the drawing to see if the ever meet?
 Let the whole class do it on their notebooks and check if they meet?
(This will help and give you a clue for going ahead)
 Ask the students that can they give example of some parallel lines from their surroundings?
Examples:
 Lines on the highway, railway tracks, lines in their notebooks, etc.
 Then repeat; Parallel Lines: two lines (that go on forever) beside each other and never intersect or touch each other.
 Ask: what would happen if railway tracks were not parallel?
 Accept answers like, “the trainwheels will not find the track to be fixed in and move hence train will be DEtracked.”
 Discuss parallel lines in given letters H, N, W (one pair, two pairs).
 Present following parallel lines patterns on Chart Paper or on board.
Development
Activity 1

Activity 2

Sum up / Conclusion
 Tell the students that today we discussed parallel and nonparallel lines.
 Ask them to describe parallel and nonparallel lines.
 How we draw parallel lines with the help of setsquare.
 Let them think and answer if any one finds any difficulty repeat the concept.
Assessment
 Draw a line using setsquares and rulers which is parallel to line PQ = 7 cm and passes through a point “5” not on PQ.
 Prepare a wok sheet with lines drawn in different directions and ask them to draw parallel lines for each of them by using setsquares.
 Teacher should also involve the students to solve exercise t the end of chapter of textbook.
Follow up
 Ask students to practice parallel and nonparallel lines on the board or on soil with pebbles and chalk.
 Assign questions from the textbook.
