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
lawn
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
15 square metres The area is = 15 m2

Area of A = 4 × 3 = 12 m2
Area of B = 3 × 2 = 6 m2
Total area = 12 + 6 = 18 m2

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

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?
