Multiples and Factors
� Multiples and Factors � � Big tiles) Three (you need MMS 6, quick response sheet and 36 � 1. List the first 10 multiples for 2 � 2. What are the factors for: � 12 b. 7 c. 25 a. � 3. � � What are the first 3 common multiples of 4 and 5
� Lesson Agenda: � Factor: A whole number that when multiplied with another number makes a product 2. Product: answer to a multiplication problem 3. Multiple: the numbers you arrive at when you skip count 4. Prime: numbers whose factors are one and themselves. They cannot form more than two different rectangles 5. Composite numbers: numbers that are not prime, can be square numbers too 6. Square numbers: numbers that can make squares 1. � �

Big Ideas � Factors are multiplied together to make products � Factors can be thought of as dimensions of a rectangle created with a particular area � Prime numbers have only two factors � Composite numbers have more than two factors � Some composites share common factors
Factors � Factors are multiplied together to make products 12 2 X 6 3 X 4 12 x 1 If numbers have more than two factors then they are COMPOSITE NUMBERS
Factor Circles Another way we can show the factors of a number is by using factor circles 12
Factor Circles 9
Dimensions of squares and rectangles � The factors can be thought of as dimensions for squares and rectangles. i. e. Two by six looks like ( 2 x 6 )
Prime Numbers � Make a rectangle with 7 tiles. How many different ones can you make? � Numbers than only have two factors, 1 and themselves, are prime numbers.
Can Composite Numbers also be Square? Place these numbers in the appropriate sections 7 10 9 36 100 22 16 25 22 Composite Prime Square
Square Numbers � If products can make squares (rectangle with 4 equal sides) it is called a square numbers. � They have an odd number of factors.
Your Turn, practice! � Practice: � MMS 6 2. 4 � S. A - #1 - 5, 14 � U. H - # 1 -5, 7, 14 � M - 1 -8, 14 � � Due end of lesson!
