Third graders measure the speed at which they can walk in order to understand speed and distance traveled. They then research the history of transportation and express data in a class timeline.

Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

Student explore estimation and measurement. For this measurement lesson, 2nd graders measure french fries, graph their data, and determine the size of french fries that is the best value. Students practice how to add prices and calculate...

Eighth graders watch segments of CBS's Street Cents and discuss approaches used on the program. They create standards for various items and learn why they are important to have. They test different fabrics to explore clothing standards.

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Learners observe water samples and measure the samples' water quality. Learners develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

High schoolers investigate the Chernobyl nuclear disaster by mapping out the winds carrying radiation and viewing a short video about the aftermath and subsequent health problems. They then calculate the amount of radiation that people...

In this measurement worksheet, students use blocks, bottletops, and icypole sticks to measure informal lengths. Students measure three objects.

Students use the Pythagorean Theorem to explore sailboat design. In this Pythagorean Theorem lesson, two sides of a triangular sail are measured, and the theorem is used to calculate the third side. A worksheet, bulletin board design,...

Eighth graders participate in the mini-metric Olympics. For this measurement lesson, 8th graders solve real-world problems that require them to calculate length, area, and volume in metric units.

Pupils determine the force of a helium balloon that allows it to rise a specific distance.  In this helium lesson students calculate the amount of paper needed to construct a weight and determine the density of a piece of paper. 

Second graders learn the proper way to take measurements, explore the properties of objects and expand their vocabulary.

Young scholars calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They create an equation of a line of best fit from a set of ordered...

Students design a cafeteria floor plan. In this area and perimeter lesson plan, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying...

Second graders work with liters and milliliters for measurement.

First graders identify coins and their value. Using a mixed set of pennies, nickels, dimes, and quarters, they sort the coins and identify the name of each coin and the value of one coin in each set. As the teacher announces a given...

Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

Students practice creating bar graphs using a given set of data. Using the same data, they create a group frequency chart and histograms. They must decide the best graph for the given set of data. They share their graphs with the...

Students explore the concept of similarity and congruence. For this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such...

Students analyze interior design as a profession. In this interior design lesson, students design their own dream bedroom and explore interior design as a profession. Students draw a scaled drawing using graph paper and appropriate...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the SSS theorem of...

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 explore the concept of time. Through discussion and artistic projects, they define time in their own words and tell how it is used to represent the seasons. Students draw a picture to portray time as it elapses during the...
