Grade Level: IX
Subject: Mathematics
Art(s) Integrated: drawing and colouring

Ideated by: Ms Rajeshwari Dutta
Executed by: Learners of Grade IX
Description: Learners were asked to draw a right-angled triangle of base and perpendicular of 1 unit to get the hypotenuse as √2 by the Pythagoras Theorem. By taking √2 as the base, the value of √3was found. Similarly, a square root spiral was formed by constructing √4, √5, √6, √7 and… so on using a ruler, compass and protractor. Then the spiral was used as the basis for an art piece.
Variations possible: The activity can also be performed by paper folding.
