Hello Antelopes, In this presentation you will find your maths, English, Spelling

and science lesson for today. The following lessons should take approximately 30-40

minutes each.

Y4: To calculate the area and perimeter of a shape.

Y5: To calculate and compare the area of squares and rectangles.

This lesson will be in two parts, one for Year 4 and the other for Year 5. Please go to the correct slide to begin

the lesson.

Maths Lesson

Year 4

What is perimeter and area?

How do we calculate the perimeter and area of a

rectangle?

length

width

length

width

Perimeter of a rectangle

= length + width + length + width

5 m

3 m Perimeter of this lawn

= 5 + 5 + 3 + 3 = 16m

The perimeter of a shape is the total length of its sides.

Area measures the space inside a 2D shape.

Area of a rectangle = length × width

Area of A = 4 × 3 = 12 m2

Area of B = 3 × 2 = 6 m2

Total area = 12 + 6 = 18 m2

Area of A = 3 × 1

In todays lesson, you are going to be working out the perimeter and area of rectilinear shapes.

However, they will involve missing lengths. Use your knowledge of other side lengths to work out what the missing lengths are before calculating the area and perimeter.

Length A and B need labelling.

In a rectangle, opposite sides are equal. Use this fact to help you work out

the missing lengths.

Go to the next slide to see this.

1.5cm

5cm 7cm b.

16cm

a.

Length A:

The whole length of the shape is 16cm.

In a rectangle, the opposite side is the same length so we need to work out what adds to 7cm to get to 16cm.

16 – 7 = 9

So… length A is 9cm

1.5cm

5cm 7cm

b.

a.

Length B:

The whole width of the shape is 5cm.

In a rectangle, the opposite side is the same length so we need to work out what adds to 1.5 cm to get to 5cm.

5 – 1.5 = 3.5

So… length B is 3.5 cm

16cm

Year 5

To compare the area of different rectangles.

To estimate the area by rounding.

All these rectangles have a perimeter of 36cm.

To create for and against arguments.

Please follow the link to listen to Miss McMillan reading ‘Chapter 5’ of Journey to the River Sea.

https://youtu.be/rxozu_InSc8

Think about the answers to the following questions:

What does Maia do?

Do you support what she does? Why?

English Lesson

Now, listen to Miss McMillan read Chapter 6:

https://youtu.be/oF_DWSuoqeQ

Activity 1:

Maia made the right choice to travel to Manaus alone.

Create for and against arguments for the statement.

Why did you do the right thing?

Why did she do the wrong thing?

FOR AGAINST

Activity 2:

In your opinion, do you think Maia was justified in sneaking away to Manaus on her own? If

you were Maia would you have done the same? Give reasons.

Apply the long ‘ei’ sound using ei, eigh or ey.

Use the link below to learn and practise the words with the ‘ei’ sound:

• Select the ‘Segment cards’ button to look at different words with the relevant sound.

• On the next slide, there are a selection of words for you to practise after you have done this.

• Then, go back on the website to ‘practise/ test’ to check your understanding of the words.

Properties of materials.

Science Lesson

Any substance that is used to make something is a material.

Natural materials such as stone, wood and cotton are used or worked with in

the way they are found in nature.

Synthetic or human-made materials are made from natural materials, but are altered with the help of heat or chemicals. Some examples include

plastics, polyester and Kevlar.

Describing Materials

Natural

Human-made

Describing materials

Activity 1: Have a look at different objects around you. Pick them up and feel them.

Or look at the picture below to choose an object. Think of words to describe each material, such as hard, soft, cold or rough.

Write down the object and the words around it.

Properties The words used to describe a

material are known as its properties.

Each material has its

own set of properties.

These properties make different materials useful for different purposes.

Activity 2: Can you match the

properties with their definitions on your Material Properties Activity

Sheet? Available on the next slide.

Using Materials

It is useful because if you know the properties of a material, you can then choose the best material for a purpose. Activity 3: Look again at the objects from activity 1. Why was each material chosen to make these things?

Why is it useful to know the

properties of a material?
