Day 1 (Do not complete if your child is in school Monday/Tuesday or Thursday/Friday)

 

Fractions – Halves of shapes and objects

 

Today we will be looking at halving.

Do you know what halving is?

How many groups will it be shared into? 2!

When we are halving or sharing, we need to split the objects or shapes into two equal groups!

What does equal mean? It means the same.

A half is one of two equal parts. When we have both halves together we have a whole!

 

Get a selection of objects that are able to be split in half. E.g. Cakes, fruit (pears, apples).

Think about if we were to share one of objects with someone in our house, how would we do it?

Does it matter where we cut it? It needs to be in the middle.

With a grownups help, cut the object evenly in the middle and look how it is now two equal halves.

Is the object split in half? YES! How do we know? There are two equal parts.

Could we have split it half another way?

If it was whole, we could have cut the cake another way and still cut it equally in half.

 

Repeat this but this time show them a pear (or something that cannot be split in half in any direction).

Cut the object in half across the middle and show them the parts. Has it cut in half?

Explain why/why not. It has been cut it in the middle so why is it not equal parts? Is there a way in which you could cut the object equally in half? (from bottom to top?)

Try it again and see if you can get two equal halves.

 

Sometimes, shapes can be split in half in more than one way. Sometimes they cannot.

 

Draw some shapes in your book. E.g. (triangle, rectangle and a square). Can you draw a line to show how you could split each shape equally in half? Once you have done this, can you draw the shapes again and think of any other ways?

When looking at the triangle, think about how it can be split in different ways but why can’t it be split straight across the middle? (Because the point is smaller than the wide base).

Day 2 (Do not complete if your child is in school Monday/Tuesday or Thursday/Friday)

 

Fractions – Finding halves of amounts

Today we will be finding half of amounts. What happens when we find half of something? We have 2 equal parts. This is the same when we find half of an amount. We must have the same number on both sides.

 

Use some amounts of objects that can easily be halved. E.g. grapes, raisins, pasta, rice.

Get an amount of your objects (Please make sure that the number of objects is able to be split equally in half).

 

e.g. 18 pieces of pasta.

We want to share these into two groups. One for you, and one for someone else in your house. So we need a plate/bowl for each person.

 

Share the pasta one piece at a time between the two plates/bowls.

‘One for me and one for you’

Once you have shared the amount between your two plates/bowls you need to work out how many each person gets. Each person gets 9!

We can then write this as a number sentence.

We started with 18 and halved it so each person got 9 pieces. Our sentence would look like this.

Half of 18 is 9!

 

You can try this with other amounts that are divisible by 2.

e.g. 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.

Please don’t go above 20.

 

 

If you fancy a challenge, you could have a go at halving amounts of money. This doesn’t mean cutting coins in half, but instead sharing out the amount of money.

For example, 16p. You can work out the answer the same way as we did before.

Get 16 objects and share them out between two plates/bowls. Then complete and say the sentence. But don’t forget this time, as we are thinking about money we need to include ‘p’! so our sentence would look like this… Half of 16p is 8p!

 

Day 3

 

 

Addition and Subtraction to 20

Fishy Game – Make 21 fish and label them 0-20

You will need to catch 2 fish at a time. You could make your own rod or you could use your hands.

1.Add or subtract the two fish that you catch.

Highest score is the winner.

2. Catch a fish - can you find a matching pair to make 20.

 

Day 4

 

 

Number bonds to 20

You will need an egg box or similar and 20 small objects (like buttons, beads, seeds or pulses)

 

Can you share the 20 objects between 2 egg holders and write down the addition facts that make 20.

 

Then try sharing them between 3 egg holders

 

Can you do it in a pattern?

 

Extra challenge – try using different numbers of seeds and egg holder spaces.

Day 5

 

Measuring length in centimetres

Have a look at the measuring power point and how to use a ruler guide in resources.

 

You will need a ruler that is 30cm long.

 

Warm up:

Have a look around one room. Can you find 5 things that are longer than 30cm and five things that are shorter than 15cm.

 

Measuring Task

 

Can you use the table in resources or write a list down yourself?

 

Find the objects to measure. Place them carefully next to your ruler so that you begin to measure them at 0cm. Make an estimate (guess) first and then measure to the nearest cm.

 

Which is the longest object?

Which is the shortest?

Can you place them in order from shortest to longest?
