Technology & computer science
Be the Computer: Tracing Variables and Loops
Students trace short programs by hand, tracking how variables change inside for loops, while loops and an if statement.
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
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.
Science
Lab Report Practice: How Does Drop Height Affect Bounce?
Students analyze provided ball-drop data: identify variables, write a hypothesis, calculate means, sketch a line graph and write a claim-evidence-reasoning conclusion.
Mathematics
Multi-Step Equations: Distribute, Combine, Solve
Students solve eight multi-step equations that need distributing, combining like terms, and moving variables, then find errors in sample work.
Science
Potato Cores and Salt Water: Analyzing Osmosis Data
Students analyze made-up class data from potato cores soaked in salt solutions, calculate percent change in mass and write a data-based conclusion about osmosis.
Social studies
Research Methods: Correlation, Experiments and Ethics
Students interpret a small data table, separate correlation from causation, design a simple experiment on paper and match ethics principles to examples.
Science
Runoff, Algae and Fish: Reading a Lake Data Set
Students analyze a made-up five-year lake data set to link nutrient runoff to algae growth, low oxygen and fewer fish, then propose a follow-up investigation and a solution.
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.
