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...

High schoolers explore using a circuit board in this physics lesson. They will analyze current and battery set up on a circuit board. Teachers check the board before the high schoolers experiment.

Teach your learners how to investigate the relationship between a central angle and an inscribed angle which subtend the same arc of a circle. The dynamic nature of Cabri Jr. provides opportunity for conjecture and verification.

Learners use technology to determine the shortest between two points in a plane. They are required to support their analytic explanations with visual illustrations.

Learners collect and analyze data regarding exponential functions of the form y = abx.  Students explore the affects of changing parameters on the graph of the function. 

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students investigate geo-profiling.  In this secondary mathematics lesson, students use geo-profiling to determine the most probable location of a criminal.  Students find the centroid of a polygon where the vertices represent...

Students explore circles. In this algebra/geometry lesson plan, students discover the formula for the area of a circle, as they investigate the ratio of the area of a circle to the radius^2.

Students investigate Newton’s Law of Cooling.  In this Algebra II/ Pre-Calculus lesson, students explore exponential regression as they conduct an experiment to simulate the temperature variations that occur as a liquid cools. ...

Students use data collection and analysis, statistics, and probability in problem-solving situations and communicate the reasoning used in solving these problems.

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Tenth graders explore the properties of the incenter of a triangle. In this geometry lesson, 10th graders construct a triangle and the angle bisectors of each angle. The dynamic properties of Cabri Jr. allow students to locate and...

Learners differentiate between translation, reflection and rotation. They explore the 3 types of transformation using Cabri Jr. and build on previous knowledge in this instructional activity.

Learners explore reflections on a coordinate plane in this lesson. They trace their hand on a grid, determine the coordinates of each point, and create a scatter plot of their points. Pupils use this information to investigate aspect...
