The distributive law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

The dividend is the amount we are dividing.

Explain how the distributive law applies to division expressions with a common divisor

Explain how the distributive law applies to multiplication expressions with a common factor

Combine division with addition and subtraction

Use knowledge of the order of operations to solve equations

In this unit pupils will explore what happens when we combine addition and subtraction with multiplication and division, bringing up the need for the order of operations. In the future unit pupils will use priority of operations with positive and integers and decimals.

In the prior unit pupils explained the use of the commutative and associative laws when multiplying 3 or more numbers. In this unit pupils will explore what happens when we combine addition and subtraction with multiplication and division, bringing up the need for the order of operations.
