Can you remember

from yesterday?

Word Problems

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?

Let’s chunk up and number the steps:

1.There are 3 people: Ravi, Elliot and Charles. They have 557 marbles altogether.

Let’s chunk up and number the steps:4.How many does Elliot have?

Each Unit is a part of the bar-model

How can we use

this information

to calculate the

number of

marbles that the

other boys

have?

EXTENSION:

Charles= 111+2 = 113

Ravi = 111 x 3 = 333
