Weight, time, length, cost, and mass are all things we can measure. Learners are introduced to the concepts they'll need to know before embarking on any measurement adventure. They are introduced to each type of measurement and types of...

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

Elementary schoolers examine the uses of rulers, scales, and measuring cups. They determine the criteria for the use of each tool and visit different areas of school to find items that can be measured with these tools. Everyone takes...

Would you measure ice water with a different tool than the height of a door? Of course! Scholars examine five measuring tasks and match them to the proper tools for the job. Three of these are length scenarios, one volume, and the last...

Learners compare the weight of the students's favorite soft toys directly and then indirectly using beads.

Students take personal fitness inventories. In this personal health lesson, students take measurements of their heights and weights. Students record the data, calculate their BMI, and then chart their physical activity.

Augment your math curriculum with posters detailing several concepts important to second grade math. Each poster features one math term from geometry, measurement, probability and statistics, computation and estimation, numbers and...

Students listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

Students utilize a balance scale. In this applied science lesson, students compare the weights of two objects using an elementary balance scale. Students balance the scale with weights to find how heavy an object is.

Learners explore the concept of weight and mass and the importance of units. Using a balance, they determine the weight of various objects in the unit of "pebbles" and in grams.

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Second graders explore liters and milliliters. They estimate volume and accurately measure the volume. Students plan a party and measure volume using liters and milliliters as part of the planning process.

Learners identify what mass is and how to measure an object with a balance in gram units. Students identify weight and how to measure with a spring scale in units of force. Learners compare the masses of two objects by placing each on...

Hydrologists create a concept map about how water is used and a sentence strip defining water and describing its unique properties. Small groups work together to fill a small milk carton and compute the mass of water inside. The next...

Students explore weight. In this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.

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.

You're going to wish you had a watermelon for this instructional activity! Class members read about watermelons and make a salad in class to sample. They also perform estimates, measurements and calculations on a watermelon. They predict...

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.
