Geometry Box Instruments

Students` Learning Outcomes

  • Use protractor, set squares straightedge / ruler to construct square and rectangle with given side(s).

Information for Teachers

Material / Resources

Writing board, chalk / marker, duster, geometry box, textbook


  • 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 feedback of students and then ask them to draw two right-angles one with protractor and other by using set-square. (Pair Activity)
  • Ask pair to exchange their notebooks and check work.
  • Then repeat the whole method once verbally.



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 understood.
  • Do the same for all the steps of drawing rectangle.


  • Make sure you don`t write steps on board just perform it.
  • Ask anyone 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 work)
  • Get checking done by exchanging copies. Make sure they are told to respect each other’s work and just put small ticks or crosses (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 does his home work best’.


Activity 2

  • Similar method will be used for square.


  • Steps to draw square are mentioned abov

Sum up / Conclusion

  • Recall process of drawing square and rectangle.


  • Repeat the key points so further strengthen student`s concepts.



o     A closed figure with four sides and sum of its all interior angles is 3600



o   All sides are of the same length.

o   Opposite sides are parallel.

o   There are four right angles.

o   Diagonals are equal



o   Opposite sides are of the same length and parallel.

o   There are four right angles.

o   Consecutive angles are supplementary.

o   Diagonals are equal.

Follow up

  • Encourage students to draw square and rectangles using different measurements.
  • Assign homework.
