High schoolers explore the concept of fractals. In this fractals activity, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students classify and measure angles.  In this angular activity, students measure, contruct, and classify angles.  They identify angles as acute, right, obtuse, and straight. 

Students recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.

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

Learners explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Learners place dots on the screen to recognize that they have created Sierpinski's Triangle.

Students explore the concept of Mandelbrot sets and Julia sets. In this Mandelbrot and Julia set lesson, students use a function integrator applet to investigate two-variable function iterations. Students use Julia set and Mandelbrot set...

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery lesson plan, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.

Students relate miniature golf to reflection of an image. In this algebra lesson, students collect and graph data as they study linear equations. They apply properties of graphing to solve real life scenarios.

Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.

Students make and fly a sled kite out of plastic garbage bags, dowel rods, and more. In this kite lesson plan, students plan the kite to have symmetry and make adjustments as they test it.

Third graders evaluate the attributes of cones. In this space shapes lesson plan, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.

Young scholars explore the concept of patterns. In this patterns lesson, students use applets to manipulate tessellations. Young scholars predict the next number in a sequence by recognizing patterns.

Fifth graders create polygons requested by their teacher. For this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.

Fifth graders collect temperature readings over a period of time, enter the information into a spreadsheet and choose the appropriate graph to display the results.

First graders explore counting and classification. They sort leaves, create graphs, write sentences for the data in the graphs, develop graphs for shapes, favorite animals, birthdays, and participate in a die prediction game.

Fourth graders calculate volume. In this volume activity, 4th graders calculate, estimate, and compare units of volume in English and metric systems.

Students gain practice reading coordinates and plotting points by participating in the Coordinates! Game. They demonstrate and test their skills with graph paper and the Maze Game.

Students listen to the teacher read "A Dreamer's Cloak." They examine the difference between squares and circles and create their own cloak by using a paper bag and different shapes.

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Students examine geometric shapes. In this geometric shape lesson plan, students examine how geometric shapes flip, turn, and slide to create a pattern. Students analyze the role that quilts played in helping slaves escape to freedom. ...

Sixth graders identify and replicate two dimensional illustrations of three dimensional objects. In this spatial visualization lesson, 6th graders practice viewing objects from various sides. Student participate in stations to view...
