Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.

In this skills review instructional activity, students answer 10 questions that spiral review volume, unit conversions, perimeter and area of an irregular figure, and sketching views from a base plan.

Students make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

Students use Geometers SketchPad to find the area and perimeter of several shapes. For this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Third graders discover elements in visual art. In this visual art lesson, 3rd graders explore the use of line, shape, and color in visual art. After reviewing works of art, students create unique art pieces. Technology resources provided.

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Sixth graders derive an original formula for calculating the area of an irregular figure.

In this galactic fact worksheet, students read through important facts about galaxies, their shapes, and distances from the Sun.

Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students follow written directions to construct their own tangram. In this tangram activity, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery rhyme. Students...

Young scholars use their hands, feet, computer, and rulers to measure the perimeter of objects. For this measurement lesson plan, students measure objects around the room and computer generated shapes.

Pupils get a bounce ball and find a Polyspot. On the teacher's signal, students underhand throw to a target. They keep their own score: one point each time they hit a target.

Students complete activities to learn about the common land features in Alaska. In this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

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

A second attack at figuring out the number of leaves on a tree, this activity makes both an excellent follow-up to version 1 and a stand-alone activity. Learners practice setting parameters and deciding acceptable estimate precision, and...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

What does popcorn have to do with math?  Seventh grade mathematicians are provided an opportunity to develop a conceptual understanding of the formula for volume and to use it as a tool to solve problems. The lesson begins with a...

Explore the concept of multiplication by using arrays. Classmates use arrays to gain a better understanding of multiplication. They break arrays apart to model the distributive property of multiplication over addition. The relationship...

Students engage in a lesson plan that differentiates between right and wrong types of observations. In order to conduct the experiment they are provided with leaves and nameless objects with different designs. The two are compared and...

Sixth graders examine the causes of the stock market crash of 1929.  In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...
