About this app

Circles and Pi is an interactive educational app designed to help elementary students visually grasp fundamental circle concepts. Through dynamic animations and adjustable sliders, learners can explore the relationship between radius and diameter, roll a circle to measure its circumference, and discover why the ratio of circumference to diameter is always approximately 3.14. It transforms abstract mathematical formulas into intuitive, hands-on visual experiments.

Use cases

  • Elementary school students learning about circle components like radius, diameter, and circumference
  • Math teachers looking for an interactive visual aid to demonstrate the concept of Pi in class
  • Parents wanting a fun, self-paced learning tool to support their children's geometry studies

Features

  • Interactive radius adjuster to see how diameter is always exactly twice the radius
  • Rolling simulator with a slider that rolls a circle one full turn to physically show the circumference
  • Pi visualization tool that fits diameters along the circumference to demonstrate why Pi is always 3.14
  • Live calculations of diameter, circumference, and ratio based on user inputs
