SQUARE ROOT SPIRAL ACTIVITY

Exploring the Beauty of Numbers through a Square Root Spiral
Mathematics becomes truly exciting when concepts come alive through creative activities. Students enthusiastically participated in a Square Root Spiral Activity, also known as the Theodorus Spiral, to understand Irrational Numbers and Square Roots in a visual and artistic way.
The Square Root Spiral is a Geometric construction that visualizes Irrational numbers (√2, √3, √4 , —-) using right-angled triangles based on the Pythagoras Theorem (square of a + square of b = square of c, where a, b and c are three sides of a right angled triangle and c being the longest side – hypotenuse).
This activity demonstrates that Irrational Numbers can be represented as physical lengths on a number line.
The activity begins with drawing a right triangle with both perpendicular sides measuring 1 unit. Using Pythagoras theorem students calculated the hypotenuse as √2. From there, they continue constructing consecutive right triangles, each time taking the previous hypotenuse as one side and adding another side of length 1 unit. This process helped students visually represent √3, √4, √5, and many more square roots in the form of a beautiful spiral.
Learning Outcomes
