Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Fifth graders examine how to make tessellations. In this tessellation lesson, 5th graders review the meaning of the word "polygon" while the teacher shows them various examples. They practice making tiling patterns or tessellation's with...

Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

Students identify polygons.  In this geometric shape instructional activity, students explore the characteristics of polygons.  They identify polygons, and classify triangles according to their sides and angles.  Students...

Third graders observe angles in their classroom and create an angle finder to represent them.In this angles lesson plan, 3rd graders classify angles as acute, obtuse, right or straight. Students find the differences and similarities in...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Middle and high schoolers identify and analyze fractals and research information using the Internet to locate information about them. They look at fractals in relation to nature and other real world situations. Pupils create several...

Students practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a graph,...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.

Students identify the measure of missing exterior angles. In this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.

Students find missing angles and sides of triangles. In this geometry lesson, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Sixth graders identify and draw two-dimensional representations of a three-dimensional object. Students investigate the views of an object and determine that three views are required (front, one side and the top). Students use these...

Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

Students explore types of water reserves. In this water conservation lesson, students brainstorm ways water are used in their homes. Students use a graduated cylinder to simulate the amount of water on Earth and the amount that humans use.

Fourth graders participate in a variety of activities dealing with animal characteristics and classifications in this multi-task lesson. They use graphic organizers, make booklets, and make models.

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.

Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Eighth graders explore three-dimensional objects (prisms, pyramids, cylinders and cones) to draw nets. They use the understanding of drawing nets to find the surface area of pyramids and cylinders.
