KS2 Maths Year 5 – 6b Multiplication and Division

Multiplication and Division

Multiplication and division are the inverse (opposite) of each other.

We can use multiples and division of smaller numbers to do longer division.

Division can be thought of as how many of a value ‘goes into’ the other.

When we use division for large numbers, we work in the opposite direction to multiplication, and see what fits into the largest place value first.

How to Multiply & Divide

What can we do now?

Now that you can do division, you can answer questions like these:

1)  What is the answer (quotient) when 755 is divided by 5?

2) Poppy has 4536 marbles, and wants to divide them evenly into 9 pots. How many marbles will go in each pot?

3)  After an earthquake the emergency services have to accommodate 9874 people. If an emergency shelter accommodates 7 people, how many will they need?
