Clarify prime numbers, composite numbers, and prime factorization with this worksheet. After looking over definitions, working through prime numbers, and making composite numbers, learners are introduced to prime factorization and the...

Older elementary students will appreciate how clearly Sal explains how to find the prime factorization of 75. He shows the complete process, taking note of numbers that are, and are not primes, and why.

Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its...

It would be difficult to explain how to write the given radical , the square root of 60, in its simplest form. It's not a perfect square so there are several steps required to break it down and get it to its simplest form. Just watch...

A factor tree? What's a factor tree? A tree of factors? A factor tree is a method use to do the prime factorization of an integer. It's not complicated. Watch the teacher as she explains the steps and shows how to write the answer as a...

Use prime factorization to find the greatest common factor of three given values. Okay. But what if there doesn't seem to be any integer that is common in all three given values? Well, then, the greatest common factor must be 1. Not sure...

Here's a quick review on how to use a prime factor tree to find the greatest common factor of two numbers. This is one of the simplest ways to find the greatest common factor. So watch this video to get a refresher on how to do prime...

Use prime factorization to find the greatest common factor of three given values. What are the factors that all three given numbers have in common? Identify them, and then multiply together to get the greatest common factor. Just like...

Use prime factorization to find the greatest common factor of four given values. What are the factors that all four given values have in common? Identify them, and then multiply together to get the greatest common factor. Just like that....

Put fractions with different original denominators in order using the least common denominator. Once she has shown how to find the least common denominator, an instructor constructs equivalent fractions that are more easily compared to...

Introduce your class to cube roots! You can show them this video, in which an instructor demonstrates how to find the cube root of a perfect cube. While this video is clear and well-made, it is appropriate only for more advanced learners...

Factoring is an important math skill, and it's often quite confusing for youngsters. This presentation does a good job of showing the basic skills and vocabulary needed to begin to understand this important process. Prime numbers,...

A teacher describes how to find the prime factors of 525. She starts by describing how to use a factor tree to describe the factors of a number. Next, she uses increasingly difficult examples to illustrate this concept.

Middle schoolers solve 10 short answer problems. They find the height of a tree using the Pythagorean theorem, find the LCM of two integers, identify irrational numbers, find the surface area of a cylinder, etc.

Here is a least common multiples instructional activity in which learners solve 12 fill in the blank and one word problem where they find the least common multiple for sets of two or three numbers. They can make lists or use prime...
