Chapter 4: Apply Multiplication and Division Facts
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.
