Introducing the Concept of Mass

Expand the the comparative language of young mathematicians with a hand-on weight measurement activity. Working independently or in pairs, children compare the weight of large wooden blocks to various other classroom objects, recording...

Break out the balances for this primary grade instructional activity on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom...

Help mathematicians estimate how many seeds are in a given vegetable or fruit. They are divided into pairs and estimate the amount of seeds in a whole fruit without seeing the inside. They then cut the fruit or vegetable in half and...

Kids can estimate weight, length, and height. Here, they circle the measurement that best describes the length, height, or weight of 10 different objects. 

Which is heavier, a ladybug or a ship? Learners will have fun with this weight comparison learning exercise, that uses visuals to help them determine which is heavier or lighter. They complete two comparisons for each. Lastly, they...

In this estimate and measure weight worksheet, students use objects on a balance and estimate how many cubes it would take to balance the scale, then measure and record. Houghton Mifflin test is referenced.

Students brainstorm words that describe the weight of objects. They pick up objects and estimate the weight. Afterward, students find the exact weight and compare U.S. units of weight to metric units. In groups, students create a chart...

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.

Kindergartenrs trace the outline of their body on butcher paper and compare their length to other classmates. They measure their outline in feet. This activity should be most-enjoyable for your little ones!

Students participate in activities in which they focus on patterns and relations that can be developed from the exploration of balance, mass, length of the mass arm, and the position of the fulcrum. They construct and use a two-pan...
