Deepen the number sense of young mathematicians by exploring the process of prime factorization. Follow along with this step-by-step presentation that explains how factor trees are used to break a composite number down into its prime...

Prime or composite, that is the question. Teach your class how to find the answer with this step-by-step presentation that defines and provides examples of each type of number. When addressing larger numbers, divisibility rules are...

When one method isn't enough to teach GCF, try two! This interactive webpage introduces factors and the prime factor tree to find the greatest common factor of two numbers. After the lesson, have learners click to try the two examples...

Divide and conquer factoring. Learners see how dividing polynomials is similar to long division of numbers. Pupils learn how to use long division of polynomials to help find factors of higher degree polynomials. They then use their...

Your algebra learners interpret algebraic expressions, in order to compare their structures, using a geometric context. They also discern how the two expressions are equivalent and represent a pattern geometrically and algebraically.
