Learners examine the effects of hearing loss. In this lesson on physical disabilities, students survey five older adults on hearing impairments. Learners pool their data and compare their results with the results from other studies about...

Students solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Third graders explore the concepts of time and consumer goods. In this telling time lesson, 3rd graders respond to questions about the passage of time and goods and services. This lesson incorporates the use a video titled...

Students identify the properties and theorems of triangles. For this geometry lesson, students construct angle bisectors using a compass and straight edge. They identify triangular similarity and congruency.

Students are introduced to modular mathematics. They start by making clocks for different bases. They use their clocks to count, using the base, and then finding the mod or remainder. They explore both positive and negative numbers with...

Students discover the Sieve of Erathosthenes. They explore a method to find all the prime numbers in a group of numbers. Using models, students practice divisibility rules while examining the difference between prime and composite numbers.

Students pick a tree they see everyday. They measure the tree's circumference and estimate its height using similar triangles. Students are introduced to Computational Science. They use computers and calculators to compute values...

Pupils explore lunar eclipses and discover how to predict an eclipse the same way that ancient people did. They examine dates of recorded eclipses and find a pattern. Students apply an algorithm to the pattern.

Students watch video segments of counting fish. They participate in counting fish in an activity.

Students design and create a graph of data they have collected on their favorite candy bars. They explore how to organize data as well.

Fourth graders watch a video about constructing bar graphs. They create their own graph and interpret it.

Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...

Students use comparisons, graphing, patterning, and sorting, and develop language skills as they explore the five senses.
