Maths – Area (Mon 27.4.20)

Good morning, Year 5!

I hope you had a lovely weekend.

As you know, I work part-time (Mondays, Tuesdays and Fridays), so Miss Coleman and Miss Carruthers will kindly respond to the blogs on Wednesdays and Thursdays. I will continue to prepare the blogs for you and will definitely look at them when I am back online on Friday (my usual working day). I just wanted to let you know in advance!

Today’s Maths Task: To continue to measure area.

Workbook: 5B
Chapter: 12 Area and Perimeter
Lesson: 7 and 8 Measuring the Are

How many different ways can we find the area of this shape? What do you think is the easiest way to find the area? If each square in the shape is 1cm², would that help? You can actually count the squares to find the area!
How many squares are there? So the area would be 32 cm².
Can we divide the larger shape up into two smaller rectangles? What would that look like? There is more than one way to divide the shape and this can help us!
If you know the lengths of the sides of each rectangle, you can multiply them together to find the area. After this, we would need to add the smaller areas together to find the total area.

Here is an example (with answers) of how to find areas of figures made up of rectangles and squares (click on image to enlarge):

As you can see, you can work out the area of a shape by dividing it into squares and then counting all the squares. This can get a bit slow for big
shapes. Take a look at this link which shows you how to work out the area of a shape.

If you need SUPPORT: Count the squares to find the area. You could also try to divide a larger shape into rectangles to help find the area. It can
also help to label the side lengths of each rectangle.

CHALLENGE:
Try to find more than one way of finding the area in each case and share these ways with us in the blog! You might even help another classmate
to learn a quicker way…
You can then use this online (and printable) activity to challenge yourself on measurement.

Marking your answers
As you and your parents now have access to Maths No Problem, I will
continue to set daily worksheets for you to complete at home. They may be  worksheets that you may have already attempted in class but that’s okay! It’s important that you revise and practise your skills. More information about how to log in to Maths No Problem can be found here.
You do not need to print these worksheets out – you can simply using your
yellow books to show your working out and write your answers. You or your parents can then mark it as you now have access to the answers. Therefore you will not be required to write your answer in the blog comments section.

Please do comment if you need help or have any questions
about the task.

Also, please read each other’s comments and help each other
out if you can! It is important we stay in touch and talk to each other about maths using mathematical language just like we did in the classroom 🙂

If you finish this activity and would like to learn more maths, please head over to our Home Learning page and scroll down to ‘Maths’ to find more websites you can enjoy.

Good luck!
