Better Lesson: Gcf and Lcm Project Gallery Walk

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...

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

Become fluent in the language of mathematics. Scholars learn to divide multi-digit whole numbers as well as see how to determine the greatest common factor and least common multiple. They also investigate how to apply the distributive...

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...

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...

Use a combination of tiling a rectangle to find area and find the greatest common factor of the lengths of two sides and the area they create. Pupils increase and decrease the sides of the rectangle before answer five questions...

Use Glencoe's Math Course 2 randomly generated self-checking quiz to test your knowledge of greatest common factors. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...

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...

Fifth and sixth graders solve 12 math problems by finding the least common multiple or least common denominator. They type the answer into the text box.

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...
