Mathematics
Angle Relationships: Find the Missing Measure
Students use complementary, supplementary, vertical, triangle and parallel-line angle facts to find missing angles and correct sample work.
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
Arithmetic Sequences and Linear Growth
Students find common differences, extend arithmetic sequences, use aₙ = a₁ + (n − 1)d, and model plant growth and savings with linear equations.
Mathematics
Completing the Square: Perfect Squares and Vertex Form
Students find the missing term of perfect-square trinomials, solve three equations by completing the square, and rewrite a parabola in vertex form.
Mathematics
Complex Numbers: The Cycle of i and Complex Arithmetic
Students discover the repeating pattern of powers of i, then add, subtract, multiply and divide complex numbers.
Mathematics
Exponent Rules and Scientific Notation Workshop
Students apply exponent rules, convert between standard and scientific notation, multiply in scientific notation and solve a travel-time problem.
Mathematics
Exponent Rules: Simplify, Match, and Fix the Mistakes
Students simplify expressions with the product, quotient, power, zero and negative exponent rules, match rules to examples, and fix common errors.
Mathematics
Exponential Growth, Decay and Logarithms: Lab Data Case Study
Students use a bacteria-growth case study, a half-life problem and compound interest to practice exponential functions, then connect exponents and logarithms.
Mathematics
Expressions and One-Step Equations: Words to Symbols
Students match word phrases to algebraic expressions, evaluate an expression, and solve one-step equations from word problems.
Mathematics
Factoring Basics: GCF, Trinomials, and Zero Products
Students factor out the GCF, factor simple trinomials and differences of squares, solve quadratics with the zero-product rule, and find factoring errors.
Mathematics
Factoring Trinomials: Factor, Expand and Catch the Error
Students factor eight quadratic expressions, check by expanding, and find the mistakes in three sample factorizations.
Mathematics
Finding Slope from Two Points
Students calculate slope from pairs of points, interpret positive, negative, zero and undefined slopes, complete a table, and find a mistake in sample work.
Mathematics
Function Notation: What Does f(x) Mean?
Students evaluate functions written in f(x) notation, complete a function table, solve for an input, judge true/false statements, and apply a taxi-fare function.
