Hands-On: Sums of Angle Measures

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...

Jump at the chance to use this resource. A kinesthetic activity has classmates jumping in several different ways (standing, single-step, and multiple-step jumps) to create handprints on poster paper taped to the wall. They measure the...

If Shaquille O'Neal wears a size-20 shoe, how big are his hands? Learners will use the average ratios of foot length to hand span to calculate the hand span of Shaq, but first, they have to collect the data! They will measure their peers...

An informative lesson contains a brief explanation of how the sum of the angles of a triangle is a line. The lesson continues with determining the missing angle in a triangle, or solving for a variable. Using the sum of the angles, the...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

In this measuring angles instructional activity, students draw hands in clock face to depict a given time. Next, they observe the angles created by the hands and determine the number of degrees. Students write proportions to solve the...

How many noodles long is your classroom? Find out when engineers of all ages explore measurement through the use of pool noodles. With the noodles pre-cut to certain metric lengths, the activities could be used to introduce the metric...

Squares, pentagons, triangles, polygons. How is it possible to figure out the sum of the interior angles of any of these multi-faceted shapes? There's got to be a formula. Of course there's a formula. That's what algebra is all about,...

How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate the number of...

Read about how Max and Ruthie measured some fun objects in their gym. Use this method to measure things in your classroom. A helpful teacher's guide and extra challenges will make this a fun lesson on measuring with nonstandard units.
