GCF and Simplifying Fractions

Give the class a prime example of using prime numbers. After reviewing prime factorization of numbers with the video, pupils use their knowledge to determine greatest common factors and least common multiples in the instructional...

A great resource for any math teacher covering multiples, factors or square roots; this learning exercise walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually...

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson plan. Using the coding formula listed, children learn to fluently estimate and...

Prepare your classes for future work by reinforcing multiples and finding least common multiples. Learners see how to identify the least common multiple of a set of numbers. The instructor shows examples including a set of two and a set...

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...

So do you really want to know how to find a rational number between two given fractions? The teacher explains how to average the two fractions to find a rational number between the two fractions. There are several steps involved in...

So do you really want to know how to find a rational number between two given fractions? The teacher explains how to average the two fractions to find a rational number between the two fractions. There are several steps involved in...

RJ instructs your sixth graders in two different methods of determining least common multiples. The first is by listing several multiples of each number, and the second is by drawing factor trees. This is an ideal flipped classroom...

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...

How do you find the factors of a given number? The teacher will show you how to use a table, test out your answers, and then write all your factors in a list. If you know the divisibility rules, that will also help you out.
