Lesson Planning of Quadrilaterals
Subject Mathematics
Grade 5th
Students` Learning Outcomes
- Use protractor, Set Squares straightedge / ruler to construct square and rectangle with given side (s)
Information for Teachers
- Follow these steps to draw rectangle of 8 cm and 3 cm.
Step 1: Draw a line of 8 cm.
Step 2: Use set-square or a protractor and draw Right angles at A and B.
Step 3: Use ruler and mark length of 3 cm on each of the right angles. Call the point C and D.
Step 4: Join C and D to complete the rectangle ABCD.
- Follow these steps to draw Square of 88 cm.
Step 1: Draw a line of 8 cm apart. Call this
![]()
Step 2: use set-Square or a protractor and draw Right angles at A and B
Step 3: Use ruler and mark length of 8 cm on each of the right angles. Call the points C and D.
Step 4: Join C and D to complete the Square ABCD.
Material / Resources
Writing board, chalk / marker, duster, geometry box, textbook
Introduction
- Can anyone tell me that why do we use set-square?
- Why do we use protractor?
- Do you remember how to draw an angle with protractor as we did for triangles?
- Do you remember how to draw right angle with set-square?
- Take verbal feed-back of students and then ask them to draw two right angles one with protractor and other by using set-square (pair activity)
- Ask pairs to exchange their notebooks and check work.
- Then repeat the whole method once verbally.
Development
Activity 1
- Collect their attention by asking to close their notebooks, books and just look at you.
- You then say step 1 verbally and draw on board.
- Repeat the step verbally once again to ensure that they understand.
- Do the same for all the steps of drawing rectangle.
- Make sure you don`t write steps on board just perform it.
- Ask any one of the students to repeat what you did?
- Then write a question on board and ask them to attempt twice once with rectangle and once with square. (Pair works)
- Get checking done by exchanging copies. Make sure they are told to respect each other’s work and just put small ticks or cross (X).
- Assign another question and ask them to attempt individually.
- Collect copies to be checked by you.
- Hence today we learnt about drawing rectangles. Let`s repeat it together. (Then repeat with the students once again)
- Wrap- up the lesson and announce that ‘we will see who his home works best’.
Activity 2
- Similar method will be used for square. Steps to draw square are mentioned above.
Sum up / Conclusion
- Recall process of drawing square and rectangle.
Assessment
- Repeat the key points so further strengthen student`s concepts.
Quadrilateral:
- A closed figure with four sides and sum of its all interior angles is 3600
Square:
- All sides are of the same length.
- Opposite sides are parallel.
- There are four right angles.
- Diagonals are equal.
Rectangles:
- Opposite sides are of the same length and parallel.
- There are four right angles.
- Consecutive angles are supplementary.
- Diagonals are equal.
Follow up
- Encourage students to draw square and rectangles using different measurements.
- Assign homework.
Thank you very much for sharing, I learned a lot from your article. Very cool. Thanks. nimabi
