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 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 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.

Young scholars 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...

Learners 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...
