Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This lesson allows for the discussion of independent and dependent variables, as...

What exactly is the fiscal cliff? What are the effects of changing income tax rates and payroll tax rates? Your learners will begin by reading news articles and examining graphs illustrating the "Bush tax cuts" of 2001 and 2003. They...

Capture the engagement of young mathematicians with this upper-elementary math lesson on measuring time and distance. Using Google Maps, students first measure and compare the distance and time it takes to travel between different...

Everyone loves a sale, and this worksheet allows learners to calculate which sale is more rewarding. The activity can be adapted for different thinking contexts. The answer key describes different answer choices, some being higher...

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Turn your classroom into a local cell phone store. Then, have your cell phone agents use linear equations to visually display three cell plans and their advantages. It makes for a great group project. Discuss how to decide which plan is...

This exercise is an opportunity for algebra learners to understand the connection between the slope of a line and points found on the line. Use similar triangles to explain why slope m is the same between any two points. Discuss with the...

Let's hope class participants don't get motion sickness. In the lesson, class members first solve motion problems using tables and graphs. They then use algebraic techniques to solve motion problems.

Is Hester Prynne a virtuous woman? To conclude a unit study of Nathaniel Hawthorne's The Scarlet Letter class members craft an argument essay in which they use the standards listed in Proverbs 31 from the Bible to judge Hester's virtues.

Using the resource, scholars work in small groups to rehearse a selected scene from Shakespeare's Macbeth. Finally, they present their interpretive dramatic readings to a group of peers or the whole class and complete a self-assessment...

Fifth graders demonstrate how to find their pulse and count the beats after a certain amount of time. In cooperative pairs, 5th graders use a stopwatch to keep track of their partner's heart rate in seconds. Pairs make a graph from their...

In this conversions and rates worksheet, middle schoolers solve 10 different word problems that include using metric conversions and rates to solve each problem. First, they determine the number of milliliters needed for the correct...

Learners explore example problems dealing with ratios and proportions. Afterward, they read story problems and solve them using ratios and proportions. This four-page worksheet contains six multi-step problems.

Are you looking for a reading resource about the efficiency of power systems? Here is one that introduces the output/input ratio, measurement of energy by joules or calories, and efficiency ratings. For STEM classes that are learning...

This math packet provides an opportunity for learners to graph two linear equations on a coordinate grid and determine the slope and y-intercept of each. They use the equation of five lines to find the slope and y-intercepts, and then...
