4th Topic 3- Strategies and properties to multiply

contains numbers and at least one

operation.

• numerical expression

• associative property

• compensation

• partial products

states that you can change the

grouping of the factors and the product

stays the same.

• distributive property

• associative property

• commutative property

Choosing numbers close to the numbers

in a problem to make the computation

easier, and then adjusting the answer

for the numbers chosen

• compensation

• commutative property

• rounding

• array

states that multiplying a sum (or

difference) by a number is the same as

multiplying each number in the sum (or

difference) by that number and adding

(or subtracting) the products

• associative property

• commutative property

• identity property

• distributive property

products found by breaking one factor in

a multiplication problem into ones, tens,

hundreds, and so on and then multiplying

each of these by the other factor.

• compensation

• partial product

• area model

• array

states that the order of factors can

be changed, but the product stays

the same.

• identity property

• distributive property

• commutative property

• associative property

a rectangle used to model multiplication

and division of whole numbers.

• distributive property

• commutative property

• area model

• array

a way of displaying objects in rows

and columns

• area model

• array

• partial product

• distributive property
