Quadratic Polynomials: The Secret Revealed

The fun filled and hands-on learning of quadratic expressions by cutting and pasting glazed papers. It was a geometrical interpretation of the factorization. All positive integers were represented by any one colour unit square and all negative integers were shown by different colour squares. Students could take different colour combinations. The value of x could also be taken as any number. As a conclusion, the students verified the factors of two quadratic polynomials with critical analysis of the concept.
