Lesson Plan : Common Multiples and Common Factor
Teacher Name: | Bridget and Blake |
Grade: | Grade 6 |
Subject: | Math |
Topic: | Common Multiples and Common Factors |
Content: | The explanation of Multiples and Factors. How to find the least common multiple and the greatest common Factor. |
Goals: | To explain the differences between a Multiple and a Factor. Demonstrate how to find the common multiples and factors of a group of numbers. Then showing how to find the least common multiple and the greatest common factor for a pair of numbers. ex. 4- 1,2,4, 8- 1,2,4,8 the common factors are 1,2,and 4 the greatest common factor is 4 ex. 4- 4,8,12,16,20..... 8- 8,16,24,32..... the common Multiples are 8,16.... the least common Multiple is 8 |
Materials: | A handout showing the definitions of Multiples, Factors, the least common Multiple, and the greatest common Factor. |
Introduction: | What are Factors? What are Multiples? How do you find the Greatest common Factor? How do you find the Least common Multiple? |
Development: | A factor of a given number is every number that divides exactly into the number. ex. factors of 10 10= 1,2,5,10 1 and itself is always factors of any number. When two or more numbers have the same factor, that factor is called a common factor. ex. 12= 1,2,3,4,6,12 18= 1,2,3,6,18 the common factors would be 1,2,3, and 6 the greatest factor is 6 when you multiply a given whole number by any other whole number, the result is a multiple of that number. ex. 3 multiples of 8= 8,16, and 24 common multiples of two numbers are multiples of both numbers. ex. 3= 3,6,9,12,15,18,21,24,27,30,33..... 5= 5,10,15,20,25,30...... the least common multiple is 30. |
Practice: | Activity with dominoes, asking to show the common multiples and factors. Then asking to show the least common multiple and the greatest common factor. |
Checking For Understanding: | Wanting to see the understanding of multiples and factors. Then making sure they know which one to look for on the multiples and the factors. |
Closure: | This is a brief run thru chapter 3 Common Multiples and Common Factors, form the Primtime book. Maybe with this the students now understand the differences between Multiples and Factors and can complete their homework without any problem. |
