Students examine and discuss typical linear equations, and the difference between a linear and nonlinear equation. They observe examples of linear equations and complete a worksheet.

Students use data from real-life models to calculate and compare the force required for an airplane of a given weight to become airborne. They use a graphing calculator to evaluate data and use the World Wide Web to access data.

Students are introduced to the basic ideas needed for understanding linear functions.

Learners investigate Newton's Second Law of Motion as they predict the effect of a payload on the amount of energy needed to lift a rocket vertically. The constraints of the weight of the equipment carried to Mars is compared to the...

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

Students examine pollen and fibers taken from a garment. They analyze pollen from new hybrids and compare it to the samples from the garment then make individual conclusions concerning the specific historical authenticity of the garment.

Students review the standards for Algebra I. Using the text, they discover two problems that match each standard and solve them showing all steps on paper. They create a PowerPoint slide for each problem and go through the correct...

Students research propulsion, graph data, and interpret the results.

Students are familiar with United States currency-dollar and cents. They are asked to compare it with currency of another country. Students explore currencies of various countries using the Internet, video, and hands-on activities. ...

Learners discuss how numbers increase when exponential growth is occurring. They view a video and compare exponential and linear growth with a graphing calculator.

Eighth graders evaluate statistical equations. They examine data from archaeologists at Jamestown, complete statistical equations using the sets of data, and graph the results.

High schoolers use the World Wide Web to access and use FoilSim. They also use the World Wide Web to access the NASA Glenn Web site for information relative to the factors involved with the flight of an airplane.

Students address the idea that human beings live within the world' ecosystems. They discuss how humans modify ecosystems as a result of population growth, technology, and consumption. Students discuss how the human destruction of...

Working with real world applications of quadratic models, students solve four practical problems requiring the use of the quadratic equation. They are guided through the process by a series of questions following each problem.

Ninth graders use FoilSim to fulfill the specifications of a given airfoil (wing) and plot and interpret graphs.

Students complete a variety of bear-related activities. They sort and graph teddy bears, distinguish between real and non-real bears and research bear life cycles and habitats.

Students solve problems involving exponential, logarithmic, and scientific notations. Using calculators, students explore investment problems. They use a formula and logarithms to determine the years to earn a particular income, figure...

Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...

Young scholars practice graphing a linear equation and a parabolic equation. They work cooperatively to select numbers, including fractions, which they will put into ordered pairs. Students explain their process to the class, discussing...

Students calculate the threshold value for the number of susceptible people needed to create an epidemic. They examine a real life flu epidemic and use the SIR model to solve the problems. Students discover they can use mathematics to...

Ninth graders assess the accuracy and reliability of current survey data and how it is represented. They design a survey, collect data, and use technology to analyze the data and present the results. Students examine scatter plots and...

Teaching unit allows students to develop key skills in expressions and equations while learning the value of these concepts through the lens of adventure sports.

This interactive game is similar to Concentration. Students must evaluate the expression in the puzzle for the given value and match it with the correct answer.

This lesson will explain how to define a variable in an algebraic expression. It is 2 of 4 in the series titled "Variables in Algebraic Expressions."
