This short video and interactive assessment activity is designed to teach fourth graders about which compound unit is shortest? (english units).

This short video and interactive assessment activity is designed to give fourth graders an overview of comparison of capacity (gallons, pints, and quarts).

This short video and interactive assessment activity is designed to give fourth graders an overview of conversion among units of measure for capacity (english units).

This short video and interactive assessment activity is designed to teach fourth graders about reading the compound units in pounds and ounces.

Students build scale models of objects of their choice. In class they measure the original object and pick a scale, deciding either to scale it up or scale it down. Then they create the models at home. Students give two presentations along the way, one after their calculations are done, and another after the models are completed. They learn how engineers use scale models in their designs of structures, products and systems. Two student worksheets as well as rubrics for project and presentation expectations and grading are provided.

The main areas of focus in the second grade math curriculum are: understanding the base-ten system within 1,000, including place value and skip-counting in fives, tens, and hundreds; developing fluency with addition and subtraction, including solving word problems; regrouping in addition and subtraction; describing and analyzing shapes; using and understanding standard units of measure; working with money and time; and introducing multiplication.

The worksheets and printables for second grade math available on this page will enhance any classroom's math curriculum. These engaging second grade math worksheets cover the basics of counting and ordering as well as addition and subtraction, and include exciting introductions to geometry and algebra for future self-assurance in math.

This short video and interactive assessment activity is designed to teach fourth graders about converting capacities using illustrations (english units).

This short video and interactive assessment activity is designed to teach fourth graders about multi-step subtraction of weights with compound units (metric units) - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about subtracting compound units in years and months.

This short video and interactive assessment activity is designed to give fourth graders an overview of conversion between units of weight (english units).

This short video and interactive assessment activity is designed to teach fourth graders about finding the different weight from tables (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about subtracting capacities in compound units (english units).

Students strengthen their communicate skills about measurements by learning the meaning of base units and derived units, including speed one of the most common derived units (distance/time). Working in groups, students measure the time for LEGO MINDSTORMS(TM) NXT robots to move a certain distance. The robots are started and stopped via touch sensors and programmed to display the distance traveled. Using their collected data, students complete a worksheet to calculate the robots' (mean/average) speeds at given motor powers.

This short video and interactive assessment activity is designed to teach fourth graders about total length in compound units (english units).

Students work as engineers to design and test trebuchets (in this case LEGO® MINDSTORMS® robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs. Specifically, they determine how far objects travel depending on their weights. As students learn about the different components of robot design and the specific function controls, they determine what design features are important for launching objects.

This short video and interactive assessment activity is designed to give fourth graders an overview of metric capacity operations.

This short video and interactive assessment activity is designed to teach fourth graders about using lists to solve multi-step problems with single units (metric capacities) - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about using pictures to balance a scale (metric units).

This short video and interactive assessment activity is designed to teach second graders about using symbol maps with compound units.

This short video and interactive assessment activity is designed to teach fourth graders about using a scale and subtraction to find weight in grams.
