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

Product

• the answer to a division problem

• the answer to a multiplication problem

• the answer to an addition problem

• the answer to a subtraction problem
