Start this activity with a brief description of how to solve absolute value inequalities. A space is provided to help classify the inequalities into types (greater than, less than, or equal to) and for learners to show how to graph their...

Practice solving linear equations by graphing. Scholars learn to solve multi-step linear equations in one variable by graphing both sides of the equation separately. They use graphing calculators to find the intersection of the graphs.

Seventh graders investigate a series of triangles, looking for patterns and generalizing what they have found. They analyze the pattern data and organize it into a table and graph. Students identify the relationship and discover the rule...

Ready to introduce your class to the coordinate plane? This website includes a detailed lesson plan that includes two interactive games to help learners practice graphing ordered pairs. The scripted discussion is a little cheesy and a...

Think critically — and linearly by applying linear equations to solve real-world problems. Young mathematicians write equations to model the profit on popcorn and cotton candy at a carnival and solve problems using these equations.

Students use the bisection method to approximate the roots of a polynomial. They evaluate functions for a given point, graph linear and quadratic functions, and recognize the elements of polynomial expressions.

Students investigate the origin of the quadratic function. In this algebra lesson, students analyze solving an equation by completing the square. They compare the early methods as compared to our method for solving quadratics.

Twelfth graders solve first order differential equations using the separation of variables technique. In this calculus instructional activity, 12th graders explain the connection between math and engineering. They brainstorm what...

Students differentiate functions.  In this differentiating functions activity, students use the quotient rule to differentiate functions.  Students use the quotient rule to differentiate rational functions such as a quadratic...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Students factor polynomials and use long division t solve problems. In this algebra instructional activity, students find the zeros of polynomials by synthetic and long division. They perform operation using complex numbers.

Twelfth graders explore Derive.  In this Calculus lesson, 12th graders investigate the menus and tools available in Derive.  In addition to the familiarization part of the lesson, students investigate Pascal’s Triangle,...

Pupils collect data for a bouncing ball and select one bounce to analyze. They explore the relationship between velocity, position and acceleration. They seek out connections between the graphs and the physical motion of the ball.

Students investigate the acceleration of a car.  In this acceleration of a car lesson, students make a scatter plot of corvette acceleration data.  Students find a model to fit the data by taking the integral of the curve...

By learning to select the best representation for three meal plans, students compare three meal plans to determine the best choice. Data for the meal plans is sorted on a table, as an algebraic equation, and graphed on a coordinate grid....

Students factor polynomial equations. In this algebra lesson, students identify the zeros of the equations. They use algebra to rewrite word problems using symbols.

Young scholars factor trinomials. In this algebra lesson, students identify the different integers making up the trinomial and use the special pattern to factor them. They continue to model the equations and how to factor correctly.

Learners perform factoring on the TI. In this algebra instructional activity, students factor equations using the FOIL method. They use the TI navigator to show each step using a visual.

In this brightness of stars worksheet, students use a given formula using the temperature in Kelvins of a star to find its brightness. Students solve 4 problems using this equation.

Young scholars recognize how parabolas are used in architecture and calculate a constant of variation.

Fourth graders are introduced to arithmetic and geometric sequences. In this mathematics lesson, 4th graders produce a variety of sequences by varying the starting number, multiplier, and the add-on number.

Eleventh graders investigate the way credit cards work when collecting interest. In this algebra lesson, 11th graders investigate the growth of interest exponentially when using a credit card. They calculate what the cheapest rate is to...

Students discuss pyrotechnics and what they have noticed about their height and speed. They think about the path which fireworks follow which is a parabola. They follow multiplication patterns to determine the Zero Product Property and...

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...
