Notes for teachers
Patterns & games of perfect square-number may be given to students
Activity No 1
On a paper make 3 columns like N , NxN & product .give some numbers under column N and students can fill the other 2 columns
- Materials/ Resources needed :- One white paper with 3 columns likeN , NxN &product.Pen or pencil to every student
- Prerequisites/Instructions, STUDENTS SHOULD PERFECTLY KNOW ABOUT MULTIPLICATION OF NUMBERS
- Multimedia resources INTERNET ,
- Website interactives/ links/ simulations Inthis web site you can play with perfect square number s from 1 to 1000 & play games with numbers.
- Process/ Developmental Questions
1) the side of a square is 15 cm .what is area of square ?
2) 121 balls are arranged in square pattern .How many balls in each row? - Evaluation
1) squqre of 15 =........
2)144 =........... writte in the form n2 - Question Corner
