Multiplying a Two Digit Number

The property states that when the order of two factors is changed, the product is the same.

Example: 7 X 8 = 8 X 7

• Commutative Property of Multiplication

• Associative Property of Multiplication

• Distributive Property

• Identity Property of Multiplication

A method of multiplying in which the ones, tens, and hundreds and so on are multiplied separately and then the products are added together.

• partial products

• place value

• factor

• product

Area Model

• model for multiplication problems, in which the length and width of a rectangle represents the factors

• model for multiplication and/or division problems, in which the length and width of a rectangle represents the factors, or quotient and dividend

• model for multiplication in which the length and width represent the multiples of each factor

• model for multiplication and/or division problems, in which the length and width of a rectangle represents the multiples of the factors

Distributive Property - Check each box that is correct

• allows you to multiply partial products

• allows you to distribute multiples before you multiply them

• allows you to multiply numbers according to their place value, then add partial products together to produce the sum/product

• allows you to multiply a sum by multiplying each addend separately and then adding the products
