Halves and Quarters

 

This week we are going to start learning about halves and quarters.

Talk to an adult or someone that is helping you with your learning, what do you think a half is and what you think a quarter is.

Let's see if this changes by the end of our learning.

 

Activity 1

 

Last term we talked a lot about sharing things equally in Division. We need to remember to share equally this term too, to help us with our new learning.

Look at these shapes. Imagine they were chocolate bars and think about which is the fairest way to share them.

 

 

Which would be the most unfair? Why?

 

If you spilt something in half, it means we spilt it into two equal parts.

Which shapes above have been split into two halves?

 

Now have a look at these shapes

 

Which shapes are half shaded?

Can you see which shapes have more than half of the shape shaded?

Can you see which ones have less than half of the shape shaded?

Did you spot that Shape B is not shared equally? The top part is a different shape to the bottom part.

Can you think of a way we could split this in half so that both parts are equal and the same?

 

Can you find a piece of string or a piece of paper and find a way to spilt it half. Don't forget each part of your paper or string must be the fair.

 

Lastly for today, can you complete the activity sheet 'Finding Halves - Shapes'

 

 

 

Activity 2

 

Remember our learning from yesterday and equal parts.

Which of these shapes is the odd one out? Why?

 

 

 

Last term you did some fantastic learning about dividing. When we want to find half of something, we are dividing or splitting it into two parts. Yesterday you did this with shapes. Today, let's do it with quantities. This means a number of objects. This will be very similar to when we divided objects last term, but this time we only want to split it in half - which means two parts.

 

 

Salma gives half her apples to each horse.

How many apples does each horse get?  Use some objects to help you if you need to. It might be good to see how many apples she has to start with.

 

Paul has some apples in a bag.

He gives 2 apples to each donkey. There are no more apples left in his bag.

How many apples were in Paul's bag?

 

Can you find 12 objects for the next task.

Start with 12 and half them. This means share them into two equal parts. How many does each part have?

 

We would say that half of 12 is 6. Did you get it right?

 

Using your objects again, can you work out what half of 10 is?

Try again with 8,6 and 4. You can write your answers down or tell your answer to an adult.

               

Which group of apples have been shared into halves?

 

 

Activity 3

 

Here I have 10 apples. I need to find half.

 

I am going to draw around half of the apples.

 

Half of 10 apples is ­  5   apples.

Use your understanding to complete 'Finding Halves - Quantities'

                          

   

Activity 4

 

You have done lots of amazing learning about halves and now we are going to learn about quarters.

Can you find a piece of paper and fold it very carefully in half. Now fold it in half again. Open it up. Can you see four equal parts? Each part is a quarter.

 

Look at these shapes

 

Can you find which shapes are split into quarters? This means they must be split into four equal parts.

 

When we split a shape into 4 equal parts, each part is called a quarter.

Even though they look different, all of these shapes below have been split into four equal parts and each shaded part is one quarter.

 

 

Can you use this understanding to help you find which of these shapes have been split into quarters?

 

 

 

Activity 5

 

Today I'd like you to practice finding quarters of different shapes.
