Simpler Math
Interactive Learning Tools
Explore mathematical ideas, investigate relationships, and see how mathematics works through interactive tools designed for learning.
These tools are built around a simple idea: mathematical understanding develops when students can see what is happening, change something, and watch how the mathematics responds.
Each tool is designed to support a specific concept — not to replace instruction, but to give students and teachers a way to investigate ideas that are difficult to explore on paper alone.
Statistics
Inference Lab
Run simulated hypothesis tests and watch p-values emerge from thousands of random trials. Supports one- and two-proportion tests, one- and two-sample mean tests, and chi-square tests.
Understanding Regression Models
Explore the least-squares regression line, correlation, and the coefficient of determination through interactive visualizations with draggable data points and live calculations.
Random Number Generator
Generate random numbers for simulations, sampling activities, and classroom demonstrations.
Geometry
3D Exploration
Explore three-dimensional figures interactively. Investigate how surface area is built from individual faces, and work through volume calculations step by step for prisms, pyramids, cylinders, cones, and spheres.
Trigonometry Exploration
Investigate the Pythagorean theorem with a draggable triangle and visual squares on each side, then explore sine, cosine, and tangent ratios with color-coded sides and live fraction displays.
Algebra
Polynomial Explorer
Explore how polynomial degree and leading coefficient shape a graph's end behavior, turning points, and zeros. Adjust coefficients and watch the graph respond — then connect what you see to the algebra.
Interactive Unit Circle
Explore how angles determine sine, cosine, and tangent on the unit circle. Toggle between radians and degrees, select special angles, and watch the trig graphs update live alongside the circle.
Calculus
