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

Young scholars 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...

Students 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.

High schoolers focus on finding solutions to situations found in everyday life. Students participate in activities to solve a system of equations, identify the system as consistent and independent, consistent and dependent or...

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...

Students identify the properties and theorems of triangles. In 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 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 use comparisons, graphing, patterning, and sorting, and develop language skills as they explore the five senses.
