In this concave and complex 2-D shapes instructional activity, students study, analyze and determine and circle which shapes out of 6 are concave pentagons.

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Young scholars investigate the properties of quadrilaterals. In this geometry lesson plan, students solve problems dealing with construction and designs. They work with quadrilaterals, midpoints and parallelograms.

In this math worksheet, students are asked to read the book that focuses upon the creation and explanation of three dimensional shapes.

Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

This lesson focuses on polygons; a polygon is a closed, flat shape that has only straight sides. Polygons can have any number of sides and angles, but the sides cannot be curved.

[Free Registration/Login may be required to access all resource tools.] This study guide focuses on polygons: convex vs concave, interior and exterior angles, and basic terminology for common polygons.

This activity will allow students to use Cabri Jr. to find the sum of the measures of interior angles of convex polygons and visually see how the Interior Angle Sum Theorem works.

This lesson explores the characteristics of various types of polygons. It includes two PowerPoint presentations that test students' understanding by grouping polygons in the correct categories.

This site talks about how to check for the intersection of polygons. Computer programs calculating intersections are presented.
