Lesson Planning of Geometry (Line and Curves)
Students` Learning Outcomes
- Differentiate between a straight line and a curved line.
- Identify straight and curved lines from the given line drawings.
- Use straightedge / ruler to draw a straight line of given length (exclude fractional lengths)
Information for Teachers
- A line is a type of geometric figure. A line is made up of various numbers of points.
- A line can be straight or curved. A straight line shows the shortest distance between two points.
- Curved line distance is greater than the straight line. A curved line is sometimes called a curve, as;
- A circle shows curved lines whereas triangle, rectangle, and square show straight lines.
- We use a ruler to draw straight lines of given lengths.
- While teaching the lesson, the teacher should also consult textbook at all steps wherever and whenever it is applicable.
Material / Resources
Writing board, chalk/marker, duster, drawing having curved and straight lines on a card sheet, worksheet
- Draw the shapes of square on the board and ask the students, are lines straight or curved? (The expected answer would be as; straight)
- Draw the shapes of circle on the board and ask the students, that line or curved. (The expected answer would be as; curved)
- Ask the students to draw straight lines on their notebooks using book, lunch box or pencil.
- Observe their work and guide them.
- Tell the students that we can draw straight line by using ruler.
- Ask the students to draw straight lines using ruler.
- They will compare these lines with the lines drawn by using books.
Sum up /Conclusion
- A line can be straight or curved.
- We draw straight line using a ruler.
- We can draw a straight line of given length using a ruler.
- Demonstrate the drawing of straight lines of the given lengths using a ruler. Ask the students to draw straight lines of the following lengths using a ruler.
a) a) 8 cm
b) b) 10 cm
c) c) 6 cm
- Observe their work and guide. Encourage the students and help the slow learners.
- Teacher is also required to involve the students in solving the problems given in the exercise at the end of unit / chapter.
- Circle the alphabets which have no curved line and put tick on all others.
