Students investigate the interior angles of a triangle. For this geometry lesson, students create the formula to calculate the angles inside a triangle. They observe the total sum of a triangles angle on the navigator.

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

Identify and make conjecture about properties of cyclic quadrilaterals. Students use the TI Navigator to create different shapes and draw conclusions.

Students calculate area, perimeter and length of rectangles. In this geometry lesson, students create different formulas for the problem they are being asked to solve. They use the navigator to move the shape around and make observations.

Students solve two functions at once. In this algebra lesson, students add, subtract, multiply and divide composition functions. They use the correct notation and substitution to get their answer.

Young mathematicians solve composition of functions. They add, subtract, multiply and divide functions and then identify the domain and range of each function. An embedded animation shows three different applications of function...

Students define and graph properties of linear equations. In this algebra lesson plan, students write systems of equations to represent functions. They relate linear equations to the real world.

Perform transformations on exponential functions! Teach your class how to perform dilation, compression, and translation. They graph exponential functions using the TI Calculator.

Young mathematicianss predict the outcome of an event. Learners solve problems using permutations and combinations. They use the TI calculator to see the different combinations and how the groupings occur.

Pupils analyze the variables in the formula of a compound interest. They model the increase or decrease of an investment using compound interest and discuss different compounding periods.

Your mathematicians solve problems using geometric series in this pre-calculus lesson. They divide a unit square into very small pieces and identify the reasoning behind the sum of a series being less than one.

Using Cabri Jr. learners construct a circle and determine the equation of the circle they drew by finding the center and the radius. Students use the distance formula to derive the equation of their circle.

High schoolers differentiate lines and angles using betweenness in this geometry lesson. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson, have your class construct similar triangles using Cabri Jr so that they share a common vertex.

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...

Eighth graders create a survey, gather data and describe the data using measures of central tendency (mean, median and mode) and spread (range, quartiles, and interquartile range). Students use these measures to interpret, compare and...

Students produce a short choreography composition. Specific guidelines and choice of music are provided. The grade/evaluation takes place in the form of video documentation and a teacher-created rubric.

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

Young scholars investigate the properties of quadrilaterals formed by angle bisectors of a given quadrilateral and quadrilaterals formed by the medians of quadrilaterals. This Cabri Jr. lesson provides opportunity for conjecture and...

Students discover music that was inspired by the spooky and bizarre. In this music of Hector Berlioz and Camille Saint-Saens lesson, students identify elements of music and listen to the Symphonie Fantastique and Danse Macabre....

Students discuss the history and importance of magnets to the world. In this magnetism lesson, students write an essay of a world without magnets.  Students may research addition information to add details about uses of magnets.

Students define pitch, measure varying amounts of water into containers, make predictions about the sounds made when striking the containers, put containers in order from highest to lowest pitch, and create their own sound patterns with...

Learners listen to, analyze, and describe music. They gain an understanding of music in relation to history and culture.

Middle schoolers examine the development of ragtime music and its relation to jazz. They participate in an online Interactive timeline and read about the history of ragtime music, listen to examples of music, and in small groups create...
