Young scholars use an on-line worksheet to experiment with patterns of tessellations in regular polygons. As students observe different shapes in the "Tessellate" Activity they complete a data table and practice making predictions for...

As the green squares are removed, a little piece of the puzzle is revealed. What is it? A square, a triangle, a cow? Have your class guess their way to identifying five different plane shapes.

How many of 2-D or plane shapes can your class identify? Can they get them all? Little learners view and review the names of nine different shapes, such as rectangle, square, triangle, and circle, to name a few.

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

In this mathematics worksheet, learners give the area and perimeter of each polygon illustrated on the sheet. There are six different polygons to measure on the sheet.

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

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. 

Students investigate the concept of angles and how they are used in geometry. They construct polygons using various types of angles and then classify them according to their physical properties. Students use a computer program in order...

Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.

Young scholars 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...

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

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

Have your class practice measuring the perimeter of various objects using this resource. Fifth graders place various-sized polygons in order (from largest to smallest). They use non-standard measuring tools to estimate the distance...

Students investigate the Napoleon triangle theory. In this polygon instructional activity, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral...

Students investigate the Sierpinski triangle and calculate the ratio and area of the triangle. In this fractals lesson plan, students calculate parts of a Sierpincki triangle. They use Google Earth to help them construct the different...

In this similar polygons learning exercise, students identify the corresponding sides of polygons.  They use proportions to solve problems.  Students determine the scale factor of similar figures.  This two-page learning...

In this geometry worksheet, learners identify the altitude, perpendicular bisector, median, angle bisector and the area of different polygons. There are 33 problems.

Second graders create a shape garden. In this polygons lesson, 2nd graders practice making shapes using a geoboard and read the book The Greedy Triangle by Marilyn Burns.  Students also design a shape garden using construction...

Students create a geometric pattern using mandalas, polygons and symmetry. In this geometry lesson, students analyze the mathematics involved in making the mandalas, including the shapes and symmetry. Students create their own mandalas...

Third graders describe 2D and 3D shapes. In this geometry lesson plan, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they...

Students identify polygons.  In this polygon people lesson, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The lesson may be extended by allowing students...

Students identify two- and three-dimensional figures and associate them with real-world objects.  In this geometry lesson, students are read The Very Hungry Caterpillar by Eric Carle and complete several activities including a chart...

Learners explore differents types of triangles and quadriaterals. In this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Learners create tangrams and discover the difference between...

Students identify shapes that are squares. In this square lesson plan, students identify the square items and then sing songs about squares.
