**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 360^{0}

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.
