In this two-step linear equations learning exercise, 7th graders solve 15 various problems that include linear equations with more than one-step. First, they need to get the variable, x, alone by subtracting/adding the whole number on...

Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...

Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...

Students study the techniques of building a bridge. They explore different type of bridges and then plan and build a bridge to specified instructions. Students draw plans, keep a budget, and prepare balance sheets during their bridge...

Students demonstrate how a whale uses echolocation to track food and identify one other animal that also uses echolocation. In this echolocation lesson, students play a game where one child (the whale) is blindfolded and gives a signal...

On this interactive site students learn to estimate lengths and distances using kilometers, explain the difference between perimeter and area, and measure the volume of a 3D object by counting the cubic centimeters.

Students will learn and reinforce skills for measuring perimeter and area of 2D shapes and measuring surface area and volume of 3D shapes.

In this activity, students perform area, surface area, perimeter, and volume.

Determine the missing side lengths to find the perimeter.

Need to freshen up on your geometric formulas? This explanation focuses on some basic formulas that should be committed to memory such as area, volume, perimeter, and more.

Determine the area of a rectangle by multiplying the sides.

Determine the area of a triangle.

Teat your knowledge of determing the area of a triangle using trigonometry.

This teaching site has interactive exercises using different types of measurement. You will measure length, capacity, area, perimeter, time, weight, temperature, and speed.

Convert metric measurements to U.S. Measurements and the reverse, too. Easy to follow tables have sections for area, length, mass,temperature and volume.

This site offers games and lessons that teach basic math concepts such as area and volume, number patterns, time, etc. Games use familiar tasks such as shopping to reinforce math concepts. While the title of each page includes an English...

Resource provides geometric formulas for area, perimeter, surface area, and volume.

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.

In this activity, students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.

What do students already know about geometry? What gaps do students have in their understanding? Students take the Unit 7 pretest in order to inform instruction.

WebMath will calculate the side length, diagonal length, perimeter, area, or volume, given the side, perimeter, diagonal, or area. This site also displays formulas for a square.

A comprehensive guide for learning all about measurement including the metric system, surface area, perimeter, volume, area, time, solid shapes, unit conversion, solved examples, and practice questions.
