Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.

Middle and high schoolers participate in a seven-part lesson creating Escher-Esque tessellations. They demonstrate their knowledge of geometric transformations after viewing a PowerPoint presentation, conducting Internet research, and...

Tenth graders investigate dilations and explore the dilation transformation before investigating the properties of a dilation using Cabri Jr. Students extend the concept of dilatation to the coordinate plane.

Learners investigate properties of similar figures. In this properties of similar figures lesson plan, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships...

For any study of upper-level geometry, this presentation could be of good use. It defines three important concepts: transformation, reflection, and rotation. Although brief, this presentation could easily be used in tandem with problems...

Use this math learning exercise to have your learners practice constructing a reflection of a shape drawn on a grid by using rotation. This simple learning exercise has six problems for the pupils to solve, and includes and answer sheet.

In this math worksheet, students practice their skills in constructing reflections of shapes that are on a grid. This worksheet has 13 problems for the students to solve, and includes an answer sheet.

High schoolers analyze characteristics and properties of two and three-dimensional shapes in this geometry lesson plan. They follow detailed directions to use the Cabri Geometry II Application on their TI-89 calculator to construct a...

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.

In this tessellations worksheet, students solve 2 word problems where they use the "make a pattern strategy" to form tessellations from geometric shapes. There is scaffolding for the problem solving strategy.

Students explore the world of art and culture, including the works of M.C. Escher. They identify and create original tessellations. Students use a wealth of interactive multimedia applications. They explore the artistic representations...

In this math activity, high schoolers practice constructing reflections of shapes already present in a grid-based graph. This simple activity has 12 problems for the students to solve, and includes an answer sheet.

Learners investigate transformations.  In this Algebra I/Geometry lesson, students explore reflections, translations, rotations and dilations.  The lesson includes examples of transformations in art, architecture, and...

In this math worksheet, they investigate the polar graph of: r = a + b sin (t), for various values of a and b. This is called a limacon and is applied to the definition of a transformation.

Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.

In this transformations worksheet, students review the terms and example diagrams for a translation, reflection, and rotation. Students then identify the coordinates for a triangle after completing the given transformations in the four...

In this transformations learning exercise, students identify the coordinates of triangle MNO after completing three translations and one reflection. Students use the triangle MNO with given coordinates to complete each transformation on...

Third graders are introduced to different types of transformations. As a class, they describe how a stuffed animal slides across the floor and use themselves to demonstrate as well. Individually, they flip and turn in different...

Ninth graders differentiate between energy waves transmitted from a quarry or mine as opposed to energy waves transmitted by an earthquake. They analyze seismograms of blast events from at least two quarries or mines. The energy waves...

Eighth graders investigate the concept of tessellations and transformations. They create patterns to demonstrate and practice the skill. Students write a description of the pattern for others to interpret. The pattern is assessed...
