Mathematics
Slope and Linear Relationships from Points and Tables
Students find slope from two points and from tables, write y = mx + b equations, and interpret slope in real situations.
THE LESSON LIBRARY
A good plan.
A better starting point.
Find a lesson that fits your subject, your students, and the time you have.
Mathematics
Slope-Intercept Form: Read It, Write It, Use It
Students read slope and y-intercept from equations, write equations in y = mx + b form from given information, and interpret a real-world line.
Science
Stoichiometry Basics: Using Mole Ratios from Balanced Equations
Students read mole ratios from balanced equations and use them to solve mole-to-mole, gram-to-gram, limiting reactant and percent yield problems.
Mathematics
Systems of Equations: Substitution and Elimination
Students solve systems of two equations by substitution and by elimination, check solutions, and use systems to solve two word problems.
Mathematics
The Quadratic Formula and the Discriminant: Solve and Predict
Students use the discriminant to predict how many real solutions each quadratic has, solve six equations with the quadratic formula, and model a falling object.
Mathematics
Two-Step Equations: Solve, Check, Catch the Mistake
Students solve eight two-step equations, check each answer by substitution, and find the errors in sample student work.
