Two-Way Tables
Explore statistics in a fun playground! Organize gender × favorite animal in a two-way table, change values to see marginal totals, find patterns using relative frequencies, and solve percentage challenges.
Pythagorean Theorem
Draw squares on a right triangle's sides to see a²+b²=c² as areas, find missing sides with b=√(c²−a²), and play with Pythagorean triples (3·4·5...)!
Quadratic Equations · Factoring & Discriminant
A playful space to set two roots, expand (x-r₁)(x-r₂)=0, and explore the number of real roots using the discriminant D=b²-4ac (solutions = x-intercepts of the parabola)!
Angles of Polygons
Change the number of sides to explore interior angles using triangles, and see why exterior angles always add up to 360°!
Prime Factors, GCD & LCM
Factorize with prime numbers and find the GCD & LCM by comparing exponents in this fun math playground!
Coordinate Plane & Proportions
A playful way to read coordinates and explore direct and inverse proportions with graphs and tables!
Linear Inequalities & Number Lines
Solve linear inequalities step-by-step and plot them on a number line (●/○) — including the negative division rule!
