How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Teach the basics of measurement and conversion with a five-lesson resource that builds an understanding of proportion and measurement conversion from elementary through high school. Initially, young scholars use ratios to determine soup...

How do you find the measure of an arc? Learners first review relationships between central and inscribed angles. They then investigate the relationship between these angles and their intercepted arcs to extend the Inscribed Angle Theorem...

Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

Your young forensic scientists add to and strengthen their measurement and conversion skills with these seven well-scaffold worksheets. Metric conversions, measuring length, area, and volume, reading thermometers, graduated cylinders,...

Unfortunately a portion of the beginning of this video is cut off. Close up views of how to use a metric ruler are displayed. Percentage error is mentioned. If you have a large class, this may provide a more practical way to demonstrate...

Degrees are not the only way to measure an angle! The third lesson in a four-part series introduces the definition of a radian. The problem videos use the definition to solve problems including converting between degrees and...

Build a basic understanding of units of measure and create a great foundation for your learners. The lesson gives a complete overview of everything measurement, from types of measurement to rounding to conversions — it has it all! 

Individuals investigate the relationship between radian and angle measurements by using an interactive to find the angle measurement for given radian measures. Users answer questions to convert between the two measurements.

Find the perfect amount of water for lemonade. Scholars solve the famous problem of measuring four liters of water using a three-liter container and a five-liter container. An interactive allows users to see each step of the solution.
