How to Explain Exponents and Radicals to Eighth Graders
Exponents are repeated multiplication. Radicals undo exponents. Once students see this relationship, the rules stop being arbitrary and start making perfect sense.
How to Explain Functions to Eighth Graders
A function is a special relationship where each input has exactly one output. This simple rule unlocks one of the most powerful concepts in all of mathematics.
How to Explain Linear Equations to Eighth Graders
Linear equations are the gateway to algebra. Once students can confidently solve for x, they've unlocked a powerful problem-solving tool they'll use throughout mathematics.
How to Explain Linear Functions to Eighth Graders
Linear functions create straight lines. Understanding slope and y-intercept gives students the power to graph, write equations, and see patterns in real-world relationships.
How to Explain Probability to Eighth Graders
What are the chances? Probability puts a number on uncertainty—from coin flips to weather forecasts to game strategies. Understanding probability helps students make better decisions.
How to Explain Rational and Irrational Numbers to Eighth Graders
Every number is either rational or irrational—and knowing which is which unlocks the entire real number system. Here's how to make this abstract concept concrete.
How to Explain Scientific Notation to Eighth Graders
The universe is too big—and atoms are too small—for regular numbers. Scientific notation is how scientists handle the extremes, and eighth graders can master it.
How to Explain Statistics to Eighth Graders
Is there a relationship between study time and test scores? Statistics gives us tools to answer questions like this by analyzing data and finding patterns.
How to Explain Systems of Equations to Eighth Graders
Two equations. Two unknowns. One solution that makes both true. Systems of equations solve real problems that a single equation can't handle.
How to Explain the Pythagorean Theorem to Eighth Graders
The Pythagorean theorem is arguably the most famous equation in geometry. Once students understand a² + b² = c², they can solve countless real-world problems involving right triangles.
How to Explain Transformations to Eighth Graders
Move it, flip it, turn it, stretch it. Geometric transformations show how shapes can change position, orientation, or size while keeping their essential properties.
How to Explain Volume to Eighth Graders
How much space does it hold? Volume answers this question for 3D shapes—and eighth grade is where cylinders, cones, and spheres join the mix.
