Rational expressions are just fancy fractions! Pupils apply fractions concepts to rational expressions. They find equivalent expressions by simplifying rational expressions using factoring. They include limits to the domain of the...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Ninth graders graph linear equations and inequalities in two variables and then, they write equations of lines and find and use the slope and y-intercept of lines. They use linear equations to model real data and define to define the...

Eleventh graders study homogeneous linear systems. In this linear system of equations lesson plan, 11th graders write linear system solutions in parametric vector form. Students also identify the connection between linear independence...

In this Algebra I/Algebra II worksheet, students determine the equation that correctly represents the relationship between the x and y values provided.  The one page worksheet contains four multiple choice problems.  Answers...

Twelfth graders investigate the capabilities of the TI-89.  In this calculus activity, 12th graders explore the parametric equation for a circle, for arc length of curves, and for trajectories.  Students investigate the...

In this Algebra II worksheet, 11th graders solve equations involving natural logarithms.  The two page worksheet contains explanation, worked examples, and four practice problems.  Answers are not included. 

In this integers activity, 9th graders solve and complete 14 different problems. First, they find a given number of consecutive integers with a given sum. Then, students determine the dimensions of a rectangle given the length and width....

In this letter symbols activity, students solve and complete 4 different types of problems. First, they circle the expressions that are the same as the one shown. Then, students find the value of each symbol. In addition, they simplify...

Students decide where and when to use parentheses. In this algebra lesson, students use parentheses to clarify a math problems and solve correctly. They use order of operation as they solve problems with integers and variable.

Seventh graders investigate the relationship between energy and matter, and measure the mass of various objects. They listen to a teacher-led lecture about potential energy, and in small groups measure the mass of various objects such...

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

Tenth graders investigate three different sets of data that relate temperature to another variable in the physical world. These illustrate linear, inverse and exponential relationships.

In this rocket launch worksheet, students solve 3 problems about the Ares 1X rocket and its launch, trajectory, and motion in both the vertical and horizontal direction.

Ninth graders explore how pendulums function.  For this pendulums lesson students complete a pendulum lab activity.
