Students manipulate a variety of materials and computer applets in order to explore area and the units used to measure it.

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Students complete computer activities about estimating if items are more or less than a given amount. In this estimation lesson plan, students also estimate measurements around the classroom.

In this Pacific Ocean worksheet, students read 2 pages about the Pacific Ocean and answer true and false questions. Students answer 10 questions.

In this lesson students will practice finding the perimeter of regular and irregular shapes with right angles and the appropriate units for measuring perimeter.

Test your knowledge of determing the area of irregular shapes.

Drawings and discussion of several methods to estimate the area of an irregular shape, like the state of Texas.

At the end of this lesson plan about formulas, students will be able to identify and apply the correct formula for a given situation, solve for any unknown component of the formulas for perimeter, circumference, and area of regular and...
