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.
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
Solving and Graphing Inequalities
Students solve one- and two-step inequalities, describe how each graphs on a number line, judge true/false statements, and write inequalities for real situations.
Mathematics
Surface Area of Prisms: Faces, Nets and Wrapping
Students find the surface area of rectangular and triangular prisms by adding the areas of faces, solve packaging problems and fix common mistakes.
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
Transformations on the Coordinate Plane: Slide, Flip, Turn, Resize
Students apply translation, reflection, rotation and dilation rules to the vertices of a triangle and to a point, and compare congruent and similar images.
Mathematics
Trig Identities: Test, Simplify, Catch the Error
Students test identity claims with numbers, use the Pythagorean identity to find missing trig values, simplify expressions, and find an algebra error.
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.
Mathematics
Two-Step Inequalities: Solve, Test and Describe
Students solve two-step inequalities, match them to word descriptions, model budget situations and correct sample student work.
