In this data vocabulary worksheet, students search for 16 graph-related words in a word search grid. Each word relates to graphing and collecting data. 

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...

Learners investigate the properties of segments formed which chords, secants, and tangents, intersect. The dynamic nature of Cabri Jr. allows high schoolers to form and verify conjectures regarding segment relationships.

Twelfth graders investigate the capabilities of the TI-89.  In this calculus lesson, 12th graders explore the parametric equation for a circle, for arc length of curves, and for trajectories.  Students investigate the symbolic...

Students investigate motion using a CBL. For this algebra lesson, students collect and graph data on a coordinate plane. They define and identify amplitude and period of conic graphs.

Young mathematicians explore the concept of triangles as they construct altitudes of triangles to find the orthocenter. Learners construct their triangles using Cabri Jr. on their graphing calculators and find that the altitudes of a...

High schoolers identify the different angles and sides of a triangle. In this geometry lesson, students identify the six trigonometric ratios. They graph the graph of each trig function and analyze it.

Find the length of an arc. Students relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Pupils graph Taylor polynomials in this calculus lesson. They observe the graphs for the expansion of Taylor polynomial functions and use the Ti calculator to help create visuals of the graphs.

Learners differentiate and calculate the length of an arc. They define an arc and relate it to the area of a circle and integrate the function to solve the equations. High schoolers use their TI calculators to graph the equation.

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.

Pupils detect the waveform of musical notes to determine the code for the "safe" in this forensics simulation lesson. They use a microphone and tuning forks along with Vernier EasyData on their graphing calculator to analyze five musical...

Young scholars construct the circumcenter of a triangle. In this constructing the circumcenter of a triangle lesson, students construct a triangle using Cabri Jr. Young scholars draw perpendicular bisectors of the sides of the triangle....

High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This lesson requires the use of Cabri, Jr.

Students relate the ratio of Pi to the diameter of a circle. In this geometry lesson, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and diameter and find...

Students examine an ISS EarthKAM image of farm land in Texas and New Mexico. They select sample region of image and count the number of fields in that region. They estimate how many fields are in the entire region.

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Students review for the Regents Exam. In this math lesson, students review core concept for the Regents exam by working a variety of problems. A printable worksheet is provided.

Students collect real world data from the Web regarding high and low tides at various locations in the United States. They find a function which models this data and make predictions on tide levels based on the information found.

In this activity, students find intercepts of circular function graphs. They also investigate the characteristics of such graphs.

This lesson was designed for our Grandparents and Special Friends day. It can be used for any visitation day, or an open house. The lesson is designed to review percent of a whole and the sector of the circle representing the percentage....

This activity provides students the opportunity to gain experience in creating circle graphs on the calculator and provides an excellent real-world review of computation with percents.

Students use ideas of ratio and proportion to investigate various ways to make a circle graph. Students create graphs to display the probabilities of the different sums that can be generated with two number cubes. [Requires Adobe Reader.]

Students can use the TI-84 Plus family to graph equations of circles.
