Let’s discover the treats of calculated and non-calculated expressions!
Maths activities help students to visualize, manipulate and reason. They provide the opportunity to make conjectures and test them and generalize observed patterns. They create a context for students to attempt to prove their conjectures. Following activities were carried out with the students of class IX.
The Spiral of The odorus:
The existence of irrational numbers was illustrated and demonstrated with the help of the Spiral of The odorus.
The Folding Strips:
Crease method enabled students to divide a strip into a specific number of equal parts (odd no. of parts) using a ruled graph paper.
The Centroid of Triangle:
To illustrate that the median sofa triangle concur at a point called the Centroid, which always lies inside the triangle. It is denoted by ‘G’. The Centroid divides each median in a ratio of 2:1.
