Week 1 - Area and Perimeter

Week 1- Area and Perimeter

 

In Maths this week, we are looking at finding the perimeter and area of 2D shapes. On the website, you will find lots of different ideas and activities that will help you learn about finding the perimeter and area. We have split these up into recommended lessons below, however, you may want to look at them in smaller (or bigger!) chunks, depending on how your brain works.

 

Perimeter

Lesson 1:

First of all, complete this BBC Bitesize lesson (https://www.bbc.co.uk/bitesize/articles/zbcnf4j) which reminds you how to work out the perimeter of a rectangle. Remember, the perimeter is the distance around the edge of a 2D shape (imagine walking all the way around the edge of it, adding up the length of each side as you go). Have a go at the activities on this page too.

 

Lesson 2:

Once you’ve completed this, have a go at this BBC Bitesize lesson (https://www.bbc.co.uk/bitesize/articles/zkhwqp3) which explains how to work out the perimeter of rectilinear (or compound) shapes.

A rectilinear shape is a shape that has straight sides and right angles. It can look like two rectangles that have been joined together. This shape looks much more complicated than a rectangle, but the method of working out the perimeter is exactly the same - you just need to add up each length as you work around the shape. Have a go at the activities on this page too.

 

Lesson 3:

If you want to complete some extra activities, have a go at the perimeter worksheets below. Try the circles sheet if you need some more practise, the triangles sheet if you want a challenge and the squares sheet if you want even more of a challenge! We’ve included the answers too so that you can check your work when you have finished.

Area

Lesson 4:

The next thing that we’re going to look at is finding the area of 2D shapes. Complete this BBC Bitesize lesson (https://www.bbc.co.uk/bitesize/articles/zh9brj6) which explains how to work out the area of shapes. Remember, you can work out the area of a rectangle by multiplying the height of the shape, by the width…     Area = height x width.

Have a go at the activities at the bottom of the BBC Bitesize page.

 

Lesson 5:

 If you want to complete some extra activities, have a go at the area worksheets we have uploaded below. Try the circles sheet if you need some more practise, the triangles sheet if you want a challenge and the squares sheet if you want even more of a challenge! We’ve included the answers too so that you can check your work when you have finished.
