Content area: Mathematics Grade: 3 Summary: The purpose of the instructional PowerPoint is to allow the students the opportunity to learn about the properties of multiplication interactively. Given a property, the students will be able to identify the correct name for the property Content Standard: Operations and Algebraic Thinking Accomplishment: Develop an understanding of the different properties of multiplication

Four Properties of Multiplication Commutative Property: The product of the equation is still the same no matter the order of the numbers Ex. 8 * 4 = 4 * 8 Associative Property: When 3 or more numbers are multiplied, the product is the same regardless of the grouping of the factors Ex. 2 * (5 * 3) = (2 * 5) * 3
4
Continued… Multiplicative Identity Property: The product of any number multiplied by 1 is that number Ex. 9 * 1 = 9 Distributive Property: The sum of 2 numbers times a third number is equal to the sum of each addend times the third number Ex. 5 * (4 + 3) = 5 * 4 + 5 * 3

WooHoo!!
8
Question 2 Which property is 9 * (5 * 8) = (9 * 5) * 8? Distributive Multiplicative Identity Multiplicative Identity Commutative Associative

Great Job!
10
Last one! Which property is 6 * (20 + 13) = 6 * 20 + 6 * 13 Commutative Associative Distributive Multiplicative Identity Multiplicative Identity
11
Way To Go!
