[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on identifying various 2D shapes in a set of figures.

Explains the basic concept of the area of geometric shapes with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

How would you find the area of a polygon or circle? Explore this concept with engaging activities at this test prep site. Here you will find detailed problem solving strategies with accompanying visuals, a reference table with formulas,...

This instructional activity will not only help students compare and contrast the concepts of area and perimeter, but it will also move toward the concept that area is maximized while minimizing perimeter with a square.

On this interactive site, students learn to identify squares, circles, and triangles.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on counting lines and curves in various two dimensional shapes.

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...

[Free Registration/Login Required] This flipchart is an introduction to geometry vocabulary and elementary geometric figures. Activities ask students to match vocabulary and definitions and label figures. Assessment questions follow.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn how to translate a figure. They examine guided notes, review examples, watch instructional videos, and try practice problems.

[Free Registration/Login may be required to access all resource tools.] Identify and describe transformations in the coordinate plane.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

[Free Registration/Login Required] This flipchart discusses plane figures and solid figures.

[Free Registration/Login Required] This flipchart discusses plane figures and solid figures. The definitions and lesson sequence are based on Scott Foresman's Grade 4 Math textbook.

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...

[Free Registration/Login Required] This flipchart helps students to analyze and compare various two-dimensional shapes according to the vertices, sides and parallel lines. It features "containers" created in Version 3 (can be used with...

[Free Registration/Login Required] This flipchart introduces basic geometric shapes and gives students practice finding geometric shapes in everyday objects.

Did you know that two-dimensional shapes are also called polygons? This lesson describes the various 2-D shapes and includes two interactive games to reinforce skills.

Using Cabri Jr. and the properties of rotations to get a true understanding of how a figure is rotated about a point.

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