Numeracy 

Here are suggested activities linked to your weekly overview for Week 7 (18.05.20). This week's focus is Area. Area may be new to you in P5, but spend some time watching the videos and looking through the PPTs as it is an easy Maths topic to master. For the lessons, you’ll have a few worksheets you can complete linked to your Numeracy group. Please make sure you choose the correct activity. You do not need to do all the worksheets for all the groups...just your group. Remember to check out Studyladder too where you will find an Area POD to work on. If you need any help or further explanations... please email your teacher. We are only too happy to help. laugh

Numeracy Lesson 1 – Introduction to Area

 

Area is quite similar to perimeter with one subtle difference. We have already looked at perimeter which was the distance around the outside of a shape. Area is the space inside the shape and how much it takes up. For your first lesson this week, we’d like you to spend some time finding the area of shapes which are drawn on squared paper. This is really simple; as all you do is count the number of squares.

The only thing you have to remember is that there is a special label for area – it is ‘centimetres squared – cm2’ or ‘metres squared – m2’ – the ‘2’ is up in the air.  

Why don’t you watch the following videos and PPTs before trying out your worksheets for today?

You could maybe use this game after to practice:

Area Counting square units

Introduction to Area

Learn how to find area of shapes by counting unit squares. #Area #Geometry #ElementaryMath #Edpuzzle

You may have noticed that the second half of the PPT looked at shapes which are irregular and do not have straight sides or may not have full squares inside the shape. For these shapes, we follow one golden rule:

 

Count any square which is a half or bigger as 1 full square and ignore the squares which are less than a half

The easiest way to work through these is to number your full squares first and then look for the other squares which look bigger than a half. Don’t panic as there is usually no ‘exact’ answer, but try to be as accurate as you can. Have a look at this video which explains it a little more and look back at the second half of the PPT.

If you half a square which is exactly a half and you have another one of these, then you can count two halves as a whole square. If you feel like you’d like to give this a go, try the following worksheets. We have also given you an Extension activity to make some Minecraft characters thinking about area.

Numeracy Lesson 2 – Using a formula to find the area

 

Yesterday we spent some time looking at the area of squares and rectangles which were drawn on squared paper. Obviously, this is not always the case. Therefore, we must find some way of finding the area of squares and rectangles if we cannot count the squares. Have a watch at the following videos/PPTs which will teach you the formula for finding the area.

Now, Mrs Boyd and Mrs Drysdale have been telling you all year how important your multiplying tables are and here we are having to use them again. Area is ‘easy peasy’…you just need to multiply the length by the width and remember that important area label. Why don’t you try the following worksheets on finding the area of squares and rectangles using the formula?

There are lots of games on Studyladder you can play to help you practice finding the area using this formula.

 

Numeracy Lesson 3 – Working with Perimeter & Area

 

So, now you are pros at finding the area of squares and rectangles, it’s time to give you a real challenge. Quite often, you’ll be asked to find both the perimeter and the area of a shape. Don’t get yourself in a pickle…just take your time and think carefully about what you have learned.

 

Perimeter = add up all the sides (cm/m/mm etc.)

 

Area = multiply length x width (cm2 / m2 etc.)

 

It can be tricky to think of both together…try playing these games to see if you can work with both perimeter and area.

Why don’t you have a go at the following worksheets taking your time and working carefully. You can do it!

Lesson 4 – Some fun with Perimeter and Area

 

 

The next few activities on ‘Perimeter and Area’ are just a little bit of fun and you can try one of them, some of them or all of them if you’d like. We’ve incorporated some Lego and Minecraft fun for you to help with getting to grips with area and perimeter.

We hope you have some fun doing these activities and if you try some of them out, don’t forget to send pictures to your teacher. We love to see what you’re up to.
