During break, he saw a circle of classmates near the library, throwing darts and counting the holes on a dartboard. Pintu wondered what they were doing but he couldn't muster the courage to ask.
He moved away from the closed circle towards the one thing that always made him happy. Numbers.
Pintu went to the library. He leafed through a book on shapes.
A teacher spotted him. "Have you ever made a circle with a compass?" he asked Pintu. Pintu shook his head. "I'm Mr. Ahmed, the senior math teacher," he said, taking out a box from a drawer. From this box, he took out a sharp, pointy thing that Pintu had never seen before.
"This is a compass. This sharp point is fixed on paper. Then you move the pencil around the fixed point or the center. The distance between the pencil and the center is always the same. And by the time you get back to where you started, you get a..." "Circle!" exclaimed Pintu.
Pintu quickly learnt to draw a circle with a compass. He drew circles of varying sizes. He learnt that the path traced by the pencil was the circumference of the circle.
