In this activity, we will be solving different problems for finding a quarter.

Below, are examples to show all the types of questions that may come up.

**1. Finding a quarter of a shape **

Here we have a selection of shapes. Which of the shapes have been split into quarters?

To answer this we must remember what it means to make quarters.

Splitting something into quarters is when something is **shared into four equal parts.** To find which shapes have been split into quarters, we need to look for which shapes have been split into four parts that are exactly the same size. To be equal they must be exactly the same.

Let's look at each shape:

A: Let's start by counting how many parts there are - there are four. Are they all the same size? Yes they are, they are equal, so this square has been split into quarters.

B: This circle is the same - it has been split into four parts which are all the same size, so it has been split into quarters.

C: This rectangle has been split into equal parts but into three parts, not four! So this has not been split into quarters.

D: This pentagon has been split into four parts but they are two different sizes, so it is not quartered.

E: This is a funny one, isn't it? If we count the parts we can see there are four parts, and yes they are equal - they are all triangles of the same size, so yes, this is split into quarters.

**2. Finding a quarter of a quantity**

Here we have 12 penguins.

What is one quarter of 12 penguins?

We know that to find one quarter we have to share the objects into four equal groups, so let's split these penguins into four equal groups!

Now, you cannot move these penguins on the screen, so grab a piece of paper and draw them!

First, draw out 12 penguins, we can just use dots to represent the penguins, like this:

Now draw four circles to share the penguins into and start sharing them out between four groups, crossing off the dots as you go:

Continue doing this until all 12 dots have been crossed off and shared equally between the circles:

To check they have been shared equally, we need to count how many are in each circle.

There are three in each circle.

As this is the same number, we know that they have been shared out equally.

So one quarter will be what is in one of the circles.

This means that a** quarter of 12 penguins is three**.

**3. Finding a quarter of a length**

This piece of string has been cut into parts and laid out:

It has been split into quarters.

Is this true or false?

Let's have a look.

In order to be in quarters it must be split into four pieces and all four pieces must be the same size.

If we count, there are four pieces of string and they are exactly the same size.

So, yes, it is true, this string has been cut into quarters!

Shall we have a go at some questions now?
