Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Students use hands-on activities to explore transformations. They view a video segment that demonstrate how M. C. Escher employed geometry and transformations to create so many of his famous drawings.

Learners examine concept of time, and explore difference between analog and digital clocks; students make art project to represent time and create a time-story problem and solution.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Students explore math functions by solving word problems in class. In this multiplication lesson, students utilize colored cubes and base blocks to visualize multiplication problems. Students identify the multiplication values within...

Third graders measure distance using nonstandard units of measure. In this measurement lesson, 3rd graders measure a given distance through the use of the game "Mother May I?" Student gather and compare data on how many "giant steps" and...

Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

Young scholars engage in a lesson that is concerned with the concept of mental math. They perform calculations as following: recognizing a half, three quarters, and tenths. Students are also challenged to extend skills to making...

Students receive a miniature pumpkin and proceed through several stations to measure a variety of physical properties. The data is entered into a data sheet and the mass and volume measurements are used to calculate density. They also...

First graders explore number sense by participating in a measurement estimation activity. In this weight lesson, 1st graders discuss the differences between measurement units, both English and Metric. Students examine a loaf of bread to...

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.

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

In this density of the human body activity, students measure several parts of the body to calculate the body volume. Students convert the body volume to body mass and body density.

Students solve problems. In this math lesson, students write solutions using LOGO commands in order to help get the turtle to the pond.

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

In this math/science worksheet, students find the balance point of a variety of objects, and complete ten problems. Students look at sketches of objects and calculate the balance point, and also use meter sticks and weights. This is an...

Students define matter, the chemical properties of matter, and the physical properties of matter. They name physical and chemical properties of matter (by classifying using a Tree Map). Students determine the mass, volume, and density of...

Young scholars investigate the density of liquids. For this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Students create packages with a maximum capacity. For this geometry lesson ,students estimate using whole numbers, decimals and fractions. They calculate length, weight and mass of packaging.

Students investigate angles through construction. In this geometry lesson, students use a protractor to identify the measurement of an angle. They identify angles cut by a transversal and two parallel lines.

Students performing a scene about pirates and spend time making a measuring meters incorporating the main character, Captain Blood to add interest. They use meter sticks measuring items from the play and record their answers in meters.

Third graders use estimation, fractions and decimals to determine the perimeter of objects in the classroom. They are given a worksheet with a list of the items on it. The worksheet has columns beside each of the items for estimation and...

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.
