Students visit a website to determine activities at three Michigan cities. They calculate the total cost of participating in the activities or visiting places such as zoos, planetariums, historic sites, and museums.

Who doesn't need to know the Fundamental Theorem of Algebra? Use the theorem to find the roots of a polynomial on a TI calculator. The class explores polynomials with one solution, no real solutions, and two solutions. This less lesson...

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.

From z-scores to probability. Learners put together the concepts from the previous lessons to determine the probability of a given range of outcomes. They make predictions and interpret them in the context of the problem.

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Through exploration of linear programming through graphs and equations of inequalities, young scholars relate linear programming to real life scenarios, such as business. Graphing and shading is also part of this exercise.

High schoolers explore trigonometric identities.   In this Algebra II lesson, students use graphing to verify the reciprocal identities.  Using Cabri Jr, high schoolers investigate the Pythagorean trigonometric identities...

Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...

Explore the concept of, and use the Ti-Nspire to, convert complex numbers into polar form. Then practice graphing complex numbers in the polar coordinate plane.

Transformations of parabolas to fit a particular quadratic equation is taught through this activity.  In this transforming parabolas to fit a particular quadratic equation activity, young scholars describe the transformations of the...

Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Young scientists explore the concept of surface tension at is applies to water. In this activity, learners use a dropper to place drops of water on a penny. Each group guesses how many drops a heads-up penny will hold, then conducts the...

Young analysts examine changes in the nutria population, vegetation density, and marsh area over time in the wetlands of Louisiana. They import data and use the TI-73 Explorer to graph and analyze the effects of nutria on marsh loss.

Solve equations by completing the square. The pupils factor quadratic equations and graph the parabola. They also identify the different terms in the equation and look for patterns.

A career in aeronautics might be calling your class members. Building from the previous two lessons in the series, learners continue analyzing the mathematics of aeronautics. Groups create a paper airplane using paperclips for balance....

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

A 13-page test contains two 40-minute sections, which provide word problems and applied analysis to cover material from pre-algebra through geometry.

Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

Students make mathematical argument using the concept of Limit. In this algebra instructional activity, student calculate the instantaneous rate of change from the linear graph. They use a TI-calculator to create a visual of the graphs.

In exploring the concept of complex roots, students find the axis of symmetry and roots of parabolas.  Then, they discuss what makes a solution complex and how to identify functions with complex roots.
