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.

Fifth graders explore common factors. In this factorization lesson plan, 5th graders discover the greatest common factor among two numbers in a game format. Students build on previous knowledge to determine the greatest common factor.

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...

Learners explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson plan, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Learners develop patterns starting with various numbers in...

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

Students investigate numbers, ways of representing numbers, relationships among numbers and number systems. They comprehend the meaning of operations and how they relate to each other.

Students explore which fractions are made real in our world. They also show the relationship of cross multiplication and equivalent fractions To reinforce fraction skills.

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...

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...

This lesson plan is for an activity using rods (Cuisenaire Bars) to help students understand the concept of factors, in particular the LCM and GCF of two numbers.
