Exponent Rules
See aⁿ as a multiplied n times, count factors to learn why aᵐ×aⁿ adds exponents and (aᵐ)ⁿ multiplies them, and play with fun multiplication, division, and power challenges!
Is it a Function?
Use a function machine to learn how inputs and outputs work, slide a vertical line over 6 graphs to test them, and play the True/False challenge!
Scientific Notation
Play and learn how changing coefficient a and exponent n in a×10ⁿ shifts the decimal point for big and small numbers, with real-life examples and conversion challenges!
Mean Absolute Deviation (MAD)
A fun stats playground to change 5 values, measure distances to the mean, and see how MAD grows as data spreads out using deviation bars!
Coordinate Plane Transformations
Translate (x+a, y+b), reflect, rotate, and scale triangles! Learn coordinate rules, congruence, and similarity, then take the challenge to guess the new coordinates.
Probability Playground
Spin spinners to learn theoretical probability (wins÷total), roll dice to see the Law of Large Numbers approach 1/6, and sum two dice to count possible outcomes!
Time, Speed, and Velocity
Drive a car to calculate speed (= distance ÷ time), and discover the difference between distance and displacement. Includes the Speed Triangle challenge!
Multiplication Formulas & Area Model
Slice squares to visualize (a+b)²=a²+2ab+b² and (a+b)(a−b)=a²−b² through area, and play with fun algebra puzzles!
Mean, Variance & Standard Deviation
Play with 5 data points on a dot plot to explore mean, deviation (sum=0), variance, and standard deviation!
Geometric Similarity: Length, Area & Volume
Change the scale factor k to explore corresponding sides, area ratio k², and volume ratio k³ using grids and cubes!
Sectors: Arc Length & Area
Play with the radius and central angle to learn arc length (= circumference × θ/360) and sector area (= circle area × θ/360 = ½rl)!
3D Shapes: Nets, Surface Area & Volume
A playful space to fold and unfold nets, exploring the surface area and volume of prisms and cylinders! (Surface Area = sum of faces, Volume = base area × height)
Saltwater Concentration (Dilution & Evaporation)
Mix salt and water to create concentrations (%), explore changes through dilution and evaporation, and play with calculating the amount of salt!
Statistics: Tables & Histograms
A fun playground to learn statistics by counting data into tables and visualizing them with histograms!
Square Roots & Irrationals (√ on the Number Line)
Learn irrational numbers in a fun playground by finding √ using square areas and locating where it sits on the number line!
Algebra Tiles (Expanding & Factoring)
Learn to expand and factor (x+a)(x+b) hands-on by playing with the areas of rectangles!
Outcomes & Probability
Learn outcomes and probability visually! Count combinations of 2 dice (6×6=36), coin tree diagrams (2ⁿ), and the sum of dice probabilities (/36).
Solving Systems Graphically
Move two lines to see how their intersection solves the system, take quiz challenges, and explore special cases like parallel and overlapping lines!
Properties of Circles (Inscribed & Central Angles)
Explore circles by measuring angles to see that inscribed angles are half of central angles, equal on the same arc, and 90° on a diameter!
Trig Ratios sin·cos·tan
Explore how sin, cos, and tan change with right triangle angles, see how (cos, sin) works on the unit circle, and discover the exact values for 30, 45, and 60 degrees!
Quadratic Parabolas
Explore quadratic functions! Change 'a' to scale and flip, move the vertex (p, q), and try to match the target parabola!
Fun with Integers
Jump along the number line to learn addition and subtraction, and use sign rules for multiplication and division. Play with negative numbers and complete the math challenge!
Equation Balance Scale
Solve linear equations by keeping the scale balanced! Add, subtract, or divide on both sides to find x.
Linear Function Playground
Change slope a and y-intercept b to see how the line moves! Includes line-matching and point-guessing games.
