Quadrilateral

Time: 40 minutes

Activity:

Students will do the following activity:
Take a square paper and cut the paper into different shapes. (The students can follow the links to understand)
2 small triangles
1 medium triangle
2 large Triangles
1 square
1 parallelogram

With the cut out shapes the students will make different shapes (like kite, rhombus, square, trapezium, parallelogram etc) and will write the name of the figures.
Or,
With help of 10/11 sticks / matches the students will make 7/8 figures (e.g.: pentagon, rectangle, trapezoid etc) and will write the name of the figures.

They will share what they did with teachers/ parents

Resource:

Students can refer to text book (Page no. 57,58, 61, 62,63)

Time: 40 minutes

Activity:

The teacher will give the following activities to the students:

Take a paper and draw a parallelogram, cut the shape and name them ABCD. fold it by AC and DB. Then the student has to find out whether diagonal DB bisects the diagonal AC at the same point E? Share with your teacher

Take a square sheet, say ABCD. Fold along both the diagonals. Is their mid-point the same? Check if the angle at E (mid-point) is 90 degree.

After going through page no. 49 of the text book the student will draw some figure of convex and concave polygon and will share it with the teachers.

Time: 60 minutes

Assessment:
To understand the family tree of Quadrilateral and its properties the student will go through the text book then they will fill in the sheet and share it with the teacher.

Think about the given problems and share the answer with your teacher.

• Your brother has made a wooden slab. He needs it to be rectangular but he is confused. In what different ways can you make sure that it is rectangular.
• Have you seen kite flying in the sky? Make a kite with a sheet of plastic or kite paper, stick and try to fly it. Take a picture and share with your teacher./li
• Is the shape of the kite same that we learnt in the text book? What is the difference? Define it and share with your teacher.
• What are the use of quadrilaterals in our life?
• The students will share the findings with their teachers/ parents.
