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.
