High schoolers use the TI-Navigator system to explore vector fields and make predictions. They also identify what a vector field is and that it represents the movement of water. Pupils try to determine where a bottle floating might have...

Students identify different parts of a triangle. In this geometry lesson, students differentiate between similar and congruent triangles. They use the navigator to crate a visual of the different parts of a triangle.

Learners analyze linear functions in this algebra lesson. They explore the meaning of slope and the slope-intercept form of a line as they investigate the effect changing parameters on the graph of a linear function.

Have the class learn about and make conjectures about a line intersecting a cubic.  In this making conjectures about a line intersecting a cubic lesson, students draw lines that intersect a cubic at three different points. ...

High schoolers explore the problem of maximizing the volume of a box by making a physical model and observing how changes in the orientation of the paper changes the volume. They use the symbolic capacity of their calculators and...

Young scholars investigate the relationship of triangles with its sides and angles. In this geometry lesson, students create visual on the graphing navigator as they study triangles. They move the sides around to create different...

Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.

Pupils investigate linear, quadratic, and exponential regressions. They plot sets of data points, determine the regression equation that best fits the data and lastly investigate the coefficient of determination.

Learners investigate relations in this algebra instructional activity. They graph the set of ordered pairs that determine a relation. Using a TI-83 Plus, your learners will enter the coordinates in a list, create a scatter plot, and...

Young scholars construct inscribed angles using Cabri Jr. They draw a circle on their graphing calculator, then construct an inscribed angle and measure its angle measures. Learners drag the inscribed angle around the circle. They make...

Pupils explore the concept of pyramids. They determine if two sides of a pyramid are perpendicular using a graphing calculator, then discuss parallel and perpendicular lines and how to determine if two lines are parallel or...

Mathematicians investigate maximizing volume by learning to explore the problem in which they seek to maximize the volume of a cone.  High schoolers solve the problem symbolically, graphically, and through the use of integration or...

High schoolers explore an application of definite integrals. They graph three functions that go through the same three points. Learners use the symbolic capacity of their calculators to find the shortest path through the three points and...

Learners find the area of a region between two curves. They integrate functions such as sin(x) and cos(x) on a given interval and find the area bounded by the two functions. Pupils use their TI-89 to aid them in finding the bounded...

Young scholars explore an application of differentiation in this calculus lesson. They investigate the ideal dimensions for a soda can and, using the symbolic capacity of the Ti-89, investigate the dimensions of the can which has the...

Middle schoolers investigate circles. For this middle school mathematics lesson, students explore the relationship between the diameter of a circle and its circumference.

Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile.  Students launch baseballs on a football field and video tape the path of the ball.

Learners complete an activity, included, of the information on asymptotes and intercepts. They also solve and complete eight questions on graphing rational functions, file included. Finally, pupils summarize vertical asymptotes,...

Students examine complex numbers. In this Algebra II lesson, students investigate two programs that involve complex numbers: the MANDELER Program and SYNDIV program.

Young scholars explore quartic functions in this calculus lesson. They investigate an application of derivatives and definite integrals, then explore the question of which of the "three bumps" of a quartic is the largest.

Pupils explore circumference manipulating Moon Pie wrapper. In this geometry lesson plan, they manipulate snack wrappers to find circumference, diameter, radius and distance.

Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

Fourth graders make models of igneous, metamorphic, and sedimentary rocks out of different types of candy and cookies.

Investigate differential equations with your class. They use the TI-89 to explore differential equations analytically, graphically, and numerically as the examine the relationships between each of the three approaches.
