Examine dilation with matrices with your class. Learners write a conjecture for how the scale factor determines the size of an image. They then use their conjecture to write a matrix multiplication problem for the illustrated...

A TI technology activity that helps learners to recognize and use the characteristic of a perfect square quadratic to complete the square. Additionally, they apply their knowledge to solve real-world problems.

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.

Explore parabolas and investigate linear and quadratic functions to solve problems symbolically and graphically. Also use parametric functions to display trajectories on a graphing calculator.

Mathematicians explore cubic functions by learning how to investigate the relationship between the x-coordinates of the three zeros of a cubic function.  The lesson also contains an application of differentiation. 

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

Learners solve linear equations. By observing the graph of each side of an equation using the TI-nspire graphing calculator, your class gains insight into solutions, as well as balancing equations and transforming linear equations....

Students solve problems with slopes. In this algebra lesson, students identify the slope of a line and relate it to the rate of change.  They graph their lines on the TI and observe changes in the lines.

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.

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

As part of their study of future tense verbs, language learners engage in activities, read fables, and sing songs. The 25-page packet includes detailed lessons, worksheets, graphic organizers, and answer keys for assessments.

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...

The class practices, on paper and/or on a TI graphing calculator the concepts of how to add, multiply, divide and subtract complex numbers using the correct property.

In this geometry learning exercise, students create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

Everyone loves a good prank! With this reading passage, Perla and her grandmother play some fun innocent pranks on one another. Kids focus on new vocabulary words, questions about the information they have read, and responding with their...

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.

Investigate the Fundamental Theorem of Algebra and explore polynomial equations to determine the number of factors, the number of roots, and investigate multiplicity of roots.

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...

Here is a TI-Navigator™ activity that allows students to review the concept of factoring and solving quadratic binomials, including a connection to graphical solutions. They enter a number such as -2 using the minus key and not 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.

What do these pictographs show? Scholars analyze three sets of data organized into pictographs, filling in several comprehension questions about each. The first one is done for them as an example, but consider going over it together to...
