5.     The students will be able to calculate square of numbers and will be able to derive a relationship between area of square and square of the number

Description Of Activity

1.     Teacher asks students to form 3 to 4 groups of students.

2.     Groups contains number of students 4, 9, 16, 25, 36…. etc.

3.     They will be instructed to stand in equal numbers of rows and columns with equal distances.

6.     Students collect the data of cricket match then collect the perfect squares from this data.

7.    Each students get a clear idea of perfect square.

Variations

1.      Students can be encouraged by measuring the dimensions, area of squares in example before multiplying and compare with squares of numbers.

2.     Students asked to calculate the area of different square shaped bodies and then compare with square of numbers.

Coaching Tips

 You can encourage the students to calculate the area of a square and verify it relate with square of numbers in the activity (see ppt).
