A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Young scholars build as many different 2-dimensional polygons as possible: triangle, square, rectangle,...

What is the difference between a star and a triangle? Its attributes of course. Discuss the basic shapes with your class, then have them practice identifying shapes by circling the one in each row that is different. 

Printing practice is essential for aiding children in developing motor control and printing skills. They practice printing by tracing and then write the letters a and d several times each.

Help your pupils explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Students describe geometric figures. They create pictures and list each shape they used to create their pictures. They discuss the importance of shapes in their lives and create ten different geometric shapes using the Drawing tools in...

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

What type of shape is this? Learners practice identifying shape attributes as they name a parallelogram and an oval and count the sides of a cube and a triangle. There are multiple-choice answers for the shape-name questions, so...

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Students explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Math whizzes examine the relationship between area and volume and the relationship between a 3-D shape and its surface area. Following discussion and practice, pupils participate in a project in which they design packaging for a new...

Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to make a...

Young scholars explore the concepts of length, perimeter, and area. In this math instructional activity, students use Shape Explorer to practice finding length, perimeter, and area.

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

An outstanding lesson on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed...

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

This is a lengthy overview PowerPoint that defines, explains, shows examples, and has practice problems about points, lines and planes.  The class will need to write many notes and there is an example of how to set up in the Cornell...

Things are really shaping up! Provide young chemists with polyatomic ion practice using an interesting interactive. Individuals complete puzzles focused on molecular geometry and complex ions.

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

If you're teaching 3rd or 4th grade math, this presentation is a must have. It defines perimeter and polygons, then describes the process by which perimeter is determined through pair share discussion and critical thinking questions....

Young mathematicians find the surface area and volume of a square pyramid and a cone. In what looks like a typical activity out of a textbook, you'll find an activity where learners find an unknown measurement of a pyramid or...

In this points, lines, planes, and space worksheet, students solve word problems dealing with points, lines, planes, and space. Students complete 20 individual problems and 20 group problems.

For this shapes puzzle, learners identify names of polygons and circular shapes. A list of 18 shapes are listed for identity.

Which shapes are considered quadrilaterals? View and learn that two dimensional shapes with four straight sides are considered quadrilateral. The rhombus, parallelogram, rectangle, and trapezium are only few of the fabulous shapes...

Using a word bank, mathematicians fill out a crossword puzzle using 9 clues. Each clue describes a shape, using details such as the number of sides, angle degrees, and the shape category. For example: "A quadrilateral with four equal...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...
