Students examine and think about various tools in their surrounding environment to facilitate development of their primary observation and sorting skills. In this tool observation lesson, students first sort a variety of tools any way...

Students examine parallax and angular measurements.  In this investigative lesson plan students calculate distances of objects and map their results.

Students complete a number of practical measuring investigations, with an emphasis on accuracy of measuring and communication of their findings. They examine how to measure by first becoming aware of the physical attributes of objects...

Fifth graders find perimeters, areas, and volumes of everyday objects and state the precision. They work in small groups in order to take measurements, perform calculations, and write a group report about the investigation.

Students plant bean seeds, watch them grow, and measure them with non-standard objects. They describe the bean's growth in a journal and record the growth on a calendar.

Students explore mathematics by participating in a nature measurement activity. In this rain lesson, students discuss the appropriate methods used in order to measure rain downpour. Students utilize a plastic bottle, tape, stones...

Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Students are asked to estimate mass, length, volume, and area.

Third graders use rulers to measure their shoe size in inches and centimeters. They then enter the class shoe measurements into an excel data base and graph the results of both to make the comparison.

Middle schoolers create two prisms out of the same paper. They calcuate the number of centimeter cubes needed to fill each prism. They discover the concept of volume.

Second graders examine the metric system. In this metric system lesson, 2nd graders compare measurements of common objects in metric units. Students compete in a garden scavenger hunt.

Students predict, plan, and gather information for a metric measuring challenge. They cooperatively measure the perimeter of their school building using appropriate tools according to a plan they devise together. Students create...

Students read an article at CNNfyi.com about Mad Cow disease. They identify and explain bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. They formulate ways to combat mad cow disease.

The FLASH program in Seattle has put together a set of questions for special education classes covering sexual education. Some of the topics include appropriate, inappropriate, self-esteem, puberty, hygiene, reproduction,  and...

Figure out what to do when there is no grid to count. Using a ruler and a sharp pencil, the narrator shows how to perform a dilation when the figure is not on a grid. The ray method works by drawing a ray from the center of dilation...

Students examine how Christopher Columbus determined his latitude.

Blend art, adolescent snacking habits, and math to create new cereal boxes. Secondary learners review scale drawings. They use this information to construct cereal boxes to scale and will compare their creation to the original product to...

Practice makes proficient! Here, scholars practice their ratio skills to convert measurements while cooking. Nine problems make up a nine-page document equipped with clear instructions and advice for successful completion while working...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

Describe where you are—and find out where you are going—with a beginning Spanish resource on directions and maps. Spanish learners repeat and practice direction words such as norte, este, and oeste, as well as measurement terms such as...

Scientists detected exoplanets by measuring how the brightness of stars changed over time. Young astronomers interpret and analyze the same data that led to exoplanet discoveries. They learn to apply light curve graphs and connect the...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

People can make a difference in the world without leaving their homes. Using an eye-opening resource, scholars complete a handout as they consider the strengths and weaknesses of the Internet as a tool for social activism. Finally,...

Students measure their classroom and determine the area. They discuss the margin of error. Each class member will write up their results separately. Students must decide what measurements to make, and attempt to measure accurately.
