Industrial Measurement: Using Micrometers in the Workplace

Your learners will enjoy this conglomerate of hands-on activities and projects that can be used in algebra one and two, geometry, and personal finance. Rich in math standards, these projects reach into learners' lives to motivate and...

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...

Explore the meaning of scale and proportion with a set of five activities that examines the topic from elementary through high school. The first lessons explore ratio by examining pictures of different sizes. The next three activities...

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...

When the tape measure will not reach, use similarity. An installment of a large playlist on geometry introduces the method of indirect measurement. Using a story of finding the distance to the sun, the video shows how to use similar...

Look up or down to find the answer.  A segment of an extensive playlist on geometry introduces angle of depression and elevation to find indirect measurements. Using trigonometric ratios, the presentation finds missing sides and angles...

Decreasing the tone, one ratio at a time. The first lesson in a series of two begins with a discussion on accuracy and precision in measurements. Using the most precise measurement instrument, pupils measure the distances from the bridge...

In an approach that meshes higher-level thinking with approachable methods, this presentation walks that fine line between mathematical rigor and applications with skill. Not only are the specific steps for finding the radian measure of...

The mechanics of measuring angles is a skill that is often taken for granted in an upper-level math class. This clear and detailed video presentation bridges the gap between identifying angles in geometry, and using their unit-circle...

While many classes memorize the radian and degree relationships for special angles in the unit circle, this presentation is uniquely grounded in the "why's" behind these common angles. With an emphasis on the geometric interpretation of...
