Chapter 4: Apply Multiplication and Division Facts

Chapter Overview:

During this chapter, students learn to:

• Find factors and multiples of whole numbers. 
• Recall multiplication and division facts thr 
• Interpret a bar graph.
• Understand how multiplication and division are related and use multiplication properties and division rules.

Chapter 4 Vocabulary:

Associative Property of Multiplication: The property that states that the grouping of the factors does not change the product.  Example: 3 x (6 x 2) = (3 x 6) x 2

Commutative Property of Multiplication: The property that states that the order in which two numbers are multiplied does not change the product.  Example: 7 x 2 = 2 x 7

Distributive Property of Multiplication: To multiply a sum by a number, you can multiply each addend by the same number and add the products.  Example: 4 x (1 + 3) - (4 x 1) + (4 x 3) = 16

fact family: A group of related facts using the same numbers.  Example: 5 x 3 = 15, 3 x 5 = 15, 15/5 = 3, 15/3 = 5

factor: A number that divides into a whole number evenly.  Also, a number that is multiplied by another number.

multiple: A multiple of a number is the product of that number and any whole number.  Example: 15 is a multiple of 5 because 3 x 5 = 15.
