The ICTS Outreach team visited HSLN Global Smart School in Hesaraghatta and conducted a short workshop for 26 students from classes 8, 9, and 10. The session focused on understanding the number pi (π). Students explored two methods of estimating pi. One method involved using a circular disc and thread to measure the ratio of the circumference and the diameter, and the other using polygons with an increasing number of sides drawn inside and outside a circle to calculate their perimeters. Through hands-on activities and visual aids, students gained insight into how pi was estimated in ancient times using geometry.
