Lesson Planning of Quadrilaterals

Subject Mathematics

Grade 5^th

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.
