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

Identify triangles by their angle measures and side lengths by looking at and measuring angle measures and side lengths. Use Cabri Jr. to construct various triangles, then manipulate the construction to create the 6 types of triangles,...

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.

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

Pupils use calculators to work independently to discover the rules for working with exponents. The instructional activity requires the use of a TI-nspire handheld and software.

Let the learners take the driving wheel! The class solves systems of linear equations and applies the concepts of systems to solve a real-world situation about parking cars and buses. They then use calculators to create a visual of their...

Class members investigate the Jim Crow Laws, Executive Order 9066, the Chinese Exclusion Act, and the Indian Removal Act to gather information about not only the challenges encountered by diverse groups of Americans, but their...

Students collect height versus time data of a bouncing ball using the CBR 2™ data collection device. Using a quadratic equation they graph scatter plots, graph and interpret a quadratic function, apply the vertex form of a quadratic...

Mathematicians use a CBR 2™ motion detector to determine their speed or velocity going down a playground slide. They also experiment with different ways to increase their speed going down the slide. Finally, learners complete the Student...

Here's a TI step by step guided instructional activity on matrices. The class enters data into the TI calculator about movie ticket sales and uses matrices as a problem solving tool. They add and multiply matrices to determine profit.

Learners investigate properties of similar figures. In this properties of similar figures lesson, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between...

Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

After a grand conversation about immigration to the United States, scholars interview a family member to learn about their journey to America. They then take their new-found knowledge and apply their findings to tracking their family...

First graders explore the theme of dental health and hygeine. They make tooth loss predictions, count lost teeth, and graph tooth loss. In addition, they listen to dental health stories, read online stories, create spreadsheets, and play...

High Schoolers explore the concept of exponential reflections. They use their Ti-Nspire to reflect the natural logarithm function over the line y=x. Students repeat the process using different exponential functions using a slider.

Transformations of parabolas to fit a particular quadratic equation is taught through this lesson.  In this transforming parabolas to fit a particular quadratic equation lesson, students describe the transformations of the parabola...

Using primary source materials including radio broadcasts, films, and interview transcripts, history students gain a better understanding of the Dust Bowl, relief efforts for farmers, and the nation's agricultural past. It includes...

Students explore American history, military strategy and scientific discovery near the end of the World War II era. They examine the principles of the Cold War, pacifism, and the desire to keep government programs secret from the...

Help your secondary reader/writers assess texts by studying press releases from Statistics Canada and drafting articles based on them. They then compare the press release, their own articles, and actual news stories they find online. I'd...

Learners explore mean, median, and mode as they model mathematics in real-world problem situations. The instructional activity requires the use of the TI 30X IIS.
