Social studies
A Tour of the Brain: Regions and Their Jobs
Students read a short passage on the brain, complete fill-in sentences with a word bank, and apply what they learned to everyday 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
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
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
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.
Technology & computer science
Function Machines: Parameters, Arguments and Return Values
Students trace short Python-style functions on paper, match key vocabulary, and write two small functions of their own.
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.
Social studies
Money and Banking: Interest, Loans and Saving
Students match the functions of money, then calculate simple and compound interest, loan costs and a bank’s lending margin.
Mathematics
Sine and Cosine Graphs: Amplitude, Period, Midline
Students read amplitude, period and midline from sine and cosine equations, build a table of values, and write equations from descriptions.
Science
Two Pathways: Following Food and Air Through the Body
Students read about the digestive and respiratory pathways, match digestive organs to jobs, put the path of air in order and explain how digestion and circulation cooperate.
