With your partner, can you:• Read the problem and highlight key words (understand the problem)• Decide what you need to work out and how (make a plan) – can you use a bar model?• Solve the problem, showing your workings out (carry out your plan)• Check your answer and be able to explain it to your partner / and the rest of the class.

Let’s chunk up and number them:1. There are 3 people: Ravi, Elliot
and Charles. They have 557 marbles altogether.
2. Ravi has 3 x as many as Elliot.3. Elliot has 2 less than Charles4. How many does Elliot have?
On the next slides I will show you how to create the bar model to help us visualise the question.
How many equal groups do we have?
What should we do with these equal groups
to find the value of one equal group?

Let’s chunk up and number the steps:
2. Ravi has 3 x as many as Elliot.
Ravi has 3 times as many as Elliott; that means we should draw 1 part to represent Elliott's marbles and 3 parts to represent Ravi's marbles in a comparison model. Do we agree?

Let’s chunk up and number the steps:
3. Elliot has 2 less than Charles.
What else do we know? - Elliott has 2 fewer marbles than Charles, which means that Charles has 2 more than Elliott. Do we agree? Why?

How can we use
this information
to calculate the
number of
marbles that the
other boys
have?

(Save your printer ink).
Some of you may complete this within the Zoom session with me.
If not, aim to complete this independently and self mark using the answers on the next
slide.
Remember your multiplicationand division methods
You can drawthe place value discs to help you or draw a bar model.
