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
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 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.
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 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.
Assessment
- Repeat the key points so further strengthen student`s concepts.
Quadrilateral:
o A closed figure with four sides and sum of its all interior angles is 3600
Square:
o All sides are of the same length.
o Opposite sides are parallel.
o There are four right angles.
o Diagonals are equal
Rectangles:
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.
