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.

Help Manuel to measure in centimeters and meters while preparing for a science class. Students can play games and then take mini-assessments to measure their understanding of the content.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students must choose the best answers to questions about the estimated lengths of objects. Includes video demonstrating a sample problem...

In this exercise, students practice comparing lengths. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to...

Students estimate the cost of building an Egyptian pyramid with modern materials and ancient building methods in this math project.

This activity gives the students the opportunity to see what an inch really looks like. It also provides them with a chance to be creative using various inch materials and to create a visual for what an inch is. It is a great lesson to...

This activity allows the user to practice estimation skills. Students use three types of estimations: counting, length, and area. An interactive activity and teacher resources are included.

This activity allows the user to compare to quantities by estimating. Students use three types of estimations: counting, length, and area. An interactive activity and teacher resources are included.

This activity allows the user to practice estimation skills by determining if a given amount is more or less than the number of objects shown, the length of a curve, or the area of a shape. An interactive activity and teacher resources...

Students practice their multiplication skills using robots with wheels built from LEGO MINDSTORMS NXT kits. They brainstorm distance travelled by the robots without physically measuring distance and then apply their math skills to...

In past times, ocean navigators tossed a piece of wood over the side of their ships and noted how long until the ship passed the wood. They used this time measurement and the length of the ship to calculate their speed and estimate how...

This lesson plan is designed to help students learn to make estimates. Resources are linked to help support the teacher and offer exploration and practice to students.

This hands-on, inquiry based lesson is an extension of the AMSTI Science Module, Solids and Liquids. Young scholars use nonstandard units to measure beans in a soup mix. Students predict how many beans will be in a scoop. Young scholars...

Conversion calculators galore! Convert just about anything from one measureable unit into another measureable unit here with over two dozen calculators. Each of the links is specific to a measureable quantity. Some examples include...

Do students have any idea of what a foot really is? This lesson will have students measuring objects and making predictions about the length of objects.

Unit reasoning helps us make sense of measurements by converting between measurement units and making reasonable estimates. For the Praxis test, we need to know common measurement units for length, time, volume, and mass, as well as how...

For this task, students use a piece of string or another tool to measure the radius of the circle and then mark off the corresponding arc length on the unit circle as many times as they need to for 0, 1, 2, 3, 4, 5, and 6 radians. They...

This site introduces students to the definition of golden ratio. It gives them a chance to estimate ratios and predict which figures are closest to the golden ratio. There is a link on this page that provides charts for students to...
