This short video and interactive assessment activity is designed to teach fifth graders about multi-step compound unit subtraction - word problems.

This short video and interactive assessment activity is designed to teach fifth graders about multi-directional conversions.

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

Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder application is in a computer's ball-type mouse—the ball itself is a type of rotary encoder. In this activity, students experiment with two rotary encoders, including one from a computer mouse and one created using a LEGO® MINDSTORMS® NXT kit. They collect data to define and graph the relationship between the motion of the rotary encoder and its output.

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

This short video and interactive assessment activity is designed to teach fifth graders about single-unit, multi-step problems - word problems.

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

This short video and interactive assessment activity is designed to teach fifth graders about subtraction in grams.

This short video and interactive assessment activity is designed to teach fifth graders about subtraction in kilograms.

These unit conversion problems provide a rich source of examples both for composition of functions (when several successive conversions are required) and inverses (units can always be converted in either of two directions).

Temperature conversions provide a rich source of linear functions which are encountered not only in science but also in our every day lives when we travel abroad. The first part of this task provides an opportunity to construct a linear function given two input-output pairs. The second part investigates the inverse of a linear function while the third part requires reasoning about quantities and/or solving a linear equation.

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 fifth graders about using the four operations with money - word problems.

This short video and interactive assessment activity is designed to teach fifth graders about multiplication and division with money.

In this less, students will list three (3) common measurement systems used in high schools as well as common unit conversion equivalencies and be able to use dimensional analysis to convert between units.

This short video and interactive assessment activity is designed to teach fifth graders about visual objects: comparing length.

Students are introduced to the nano-size length scale as they make measurements and calculate unit conversions. They measure common objects and convert their units to nanometers, giving them a simple reference frame for understanding the very small size of nanometers. Then, they compare provided length data from objects too small to measure, such as a human hair and a flea, giving them a comparative insight to the nanotechnology scale. Using familiar and common objects for comparison helps students understand more complex scientific concepts.
