Facts and Definitions

Lesson 1: Mastering More Multiplication Facts

• Zero property of multiplication: math law that states that when multiplying a number by zero, the product is always zero
• One property of multiplication: math law that states that when multiplying a number by one, the product is always the number itself; also called the identity property of multiplication

Lesson 5: Associative Property of Multiplication

• Associative property of multiplication: math law that states that when you multiply more than 2 numbers, it doesn't matter which group of numbers you multiply first

Lesson 6: Distributive Property of Multiplication

• Distributive property of multiplication: math law that states that when given a multiplication problem, it's possible to break a factor down into easier numbers, find the products of the other factor with those easier numbers, and then add those products together to find the product of the original problem

Lesson 7: Reviewing Properties of Multiplication

• [none]

Lesson 8: Revisiting Division

• Division: mathematical operation used to split a number into equal groups, find the number of groups, or find the number in each group
• Dividend: the number being divided (8÷2=4)
• Divisor: the number by which the dividend is being divided (8÷2=4)
• Quotient: the answer to a division problem (8÷2=4)

Lesson 9: Multiplication and Division Facts Practice

• If you divide a number by itself, the quotient is 1 (for example, 5÷5=1)
• If you divide a number by 1, the quotient is the original number (for example, 5÷1=5)
