Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Eighth graders investigate the concepts that are related to measurement while focusing upon weight, mass, and capacity. They estimate the weight and mass relationship that is found in different problems. Students compare and contrast one...

Fourth graders explore unit conversions. They create visual models of measurement units, identify tables of equivalent units and make simple conversions with in a measurement system. Students produce charts that identify units of measure...

Third graders engage in a lesson that is concerned with the estimate and approximation of different masses. They weigh different objects and compare the different measurements and then use a balance to compare them. Students define the...

In this metric unit worksheet, students compare metric units, finding missing numbers, then choose the best unit for measuring given items. Students then estimate. Houghton Mifflin text is referenced.

Students measure and record weights and heights and compare to others in the class as they find out more about their bodies.

Fifth graders study the sizes of pumpkins. They measure and record the diameters of pumpkins. They create five subtraction problems and solve them. They weigh their pumpkins, record the data and select two pumpkins to make a graph of...

In this mass measurement instructional activity, students find the missing numbers by converting the metric units of mass. Students then study the pictures and choose the better estimate of the mass of each. Students compare the final...

Students observe a demonstration of regular soda versus diet soda.  In this exploring density instructional activity students complete a lab on density and present a PowerPoint presentations of their results.

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Middle schoolers examine what a healthful diet is, and examine their own eating habits to see if they are getting the right foods to stay healthy.  In this eating right lesson students keep track of what they eat for several days...

Third graders study partial-products algorithms. In this math lesson, 3rd graders use an algorithm to find the product of factors. Students discuss the relationships between multiplication and division.

Fourth graders measure cups, quarts, and liters.

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 determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Students practice converting units of measurement using the ladder method.  In this metric conversion lesson students practice converting metric measurements and filling out the worksheet. 

Fifth graders use metric measurement to study the amount a bison eats. In this measurement lesson, 5th graders watch a video about bison and discuss the amount of food they eat. Students weigh their food trays at lunch and complete a...

This metric system tutorial is compared to the U.S. standard system so that students can comprehend the measurement of length, volume, mass and the like.
