Web is expanding with information and creative tools for explorations. It has become easier for teachers to integrate readily available tools with classroom teaching. There are so many interesting tools which may be clubbed with teaching of Mathematics for creating not only interest in the subject but also extending a scope for further exploration. Say, for example when we are talking about Prime numbers in a classroom. Prime numbers are positive, non-zero numbers that have exactly two factors .Children normally see them upto 200 or a maximum of upto 500 as it is not expected from them to create a list by manual division process. And sometime they are not sure of correctness of what they have obtained.
I used Prime number calculator for checking whether a given number is Prime or not . This tool helped in finding next largest and next smallest prime numbers of a number. Prime number charts are created for displaying in classroom.
