Factors for Grade 6: HCF, GCD and GCF

Find the common denominator between prime factors, factor trees, and the distributive property. Scholars learn to find the least common multiple and greatest common factor of pairs of numbers. They rotate through stations to connect...

Learners are asked to find multiples and common multiples of two numbers. They must take their findings and find a pattern between the numbers and explain their reasoning. Use this resource with The Florist Shop activity in this series...

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 worksheet. The...

Learning about factors and multiples is all fun and games with this simple math activity. The lesson plan begins with the teacher and class playing the Factor Game together as students figure out the rules and uncover key...

Show your students this presentation to help them understand how to add fractions with like denominators. Sal adds 3/15 to 7/15 and then simplifies his answer. He uses drawings and multiple colors to show the actual process.

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...

By creating a list of factors for two numbers, it is easier to see the greatest common factor. Each question in an interactive resource asks pupils to identify the greatest common factor for the numbers 24 and 36 in several...

Beginning with a description that sets the stage, learners are asked to break down the numbers 42 and 63 to find the greatest common denominator using factor trees. As they work through the factoring process, young mathematicians are...

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...

All that work put into prime factorizations won't go to waste. An illuminating video describes how to determine the least common multiple and greatest common factor of two numbers using the prime factorizations. Learners see how to use a...
