Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

Fifth graders duplicate patterns, guess pattern results and identify the symmetries created. They are given an instructional handout, 5th graders replicate the patterns demonstrated by folding the paper and punching the appropriate...

Students observe, speculate, analyze and evaluate conclusions about Mississippi River locations as well as illustrate their findings in drawings. They enhance themselves with their surroundings and landscape pictures at various places...

Students use funnels to put the five solid materials into clear bottles with caps. They observe how the particulate materials look, sound, and move when they shake and roll the bottle. Finally, students write "sound and touch" poetry.

Students research inventors and inventions and their impacts. In this invention instructional activity, students research inventions and their affects in good and bad ways.

I love graphic organizers. My students will increase their vocabularies by learning more 2D shape terms through the use of a graphic organizer.

Look at the properties of 2D shapes to see which shapes can belong to the same group. Includes hints.

Students will use their knowledge of plane figure attributes to create and view shapes by cutting and rotating shapes to stimulate discussions on names and attributes of various shapes they do not regularly encounter.

This tutorial provides illustrations for regular 2-D shapes as well as a definition for polygons and for regular polygons.

In this activity, students will explore the properties of rotations and the relationships between the original and image figures.

Sports such as hockey, football, basketball and tennis use balls of different sizes. Can you arrange a selection of different balls in a line each touching the next to make the shortest line? This activity offers opportunities for...

You will enjoy this shape game. It tells you the name of a shape and all you have to do is click on the correct shape. If you get confused you can have another try.

Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...

Classify shapes based on pictures or attributes, such as angle types and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Based on building a hexagon, this activity from the Math Forum collection focuses on using different combinations of pattern blocks to create a hexagon. An online activity, pencil and paper method, literature connections, and a...

After reviewing the properties of different quadrilaterals, students answer questions about each type.

Students learn how to categorize plane figure polygons using Venn Diagrams with this computer based tool.

This task challenges a student to demonstrate understanding of the concept of two dimensional shapes and their properties.

This two-part geometry lesson plan has students identify, describe, and classify two-dimensional shapes. Students engage in hands-on activities including identifying shapes in the classroom, creating patterns with shapes, identifying...

This lesson demonstrates how to determine properties of quadrilaterals by using triangles. It is 5 of 5 in the series titled "Using Triangles to Examine Quadrilaterals."

Discover how the geometric shape of an object directly relates to its usefullness in this math challenge from the NCTM Math Challenges for Families collection. A one page activity that you can print or download.

Identify quadrilaterals based on pictures or attributes. Quadrilaterals included are parallelograms, rhombuses, rectangles, and squares. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

This website has basic definitions for most polygons, regular and irregular.
