Find the greatest common factor of numbers. Learners review prime and composite numbers and how to find the prime factorization of a number. They also review the greatest common factor, least common multiple, and learn new ways to find...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Sixth graders practice Least Common Multiple in fractions. For this fraction lesson, 6th graders look at two different fractions and find a common denominator. They sing a song to memorize mean, median, and mode. 

Students solve problems using the GCD and LCM. In this algebra activity, students factor and simplify equations using the greatest common and least common factors and multiples. They factor integers in pairs.

Students use Venn diagrams to solve prime number and factorization problems. In this multiplication lesson, students watch a video and use a Venn Diagram to help them solve a pizza math activity that uses prime factorization. Students...

Become fluent in the language of mathematics. Scholars learn to divide multi-digit whole numbers and determine the most significant common factor and the least common multiple. They also investigate how to apply the distributive property...

High schoolers solve a system of two unknowns.  In the Algebra lesson, students use a on line computer applet/program to solve a system by the elimination method.  The student's work is self checking, giving immediate...

Students investigate the associative property of addition. In this associative property of addition lesson, students work in pairs and build addition problems with six blocks. They sit on either side of a desk so that they can "read" the...

Fifth graders review adding, subtracting, multiplication and division of fractions and decimals through a variety of activities and exercises.

Eighth graders explore Excel and discover rules of divisibility for the numbers 2, 3, 4, 5, 6, 9, and 10; students examine multiples of 2 using pencil/ paper, then create a chart in Excel that will allow them to more easily see patterns...
