Maths

Spend 10 minutes on TT Rock Stars. 

We’re in the middle of a Year Group Battle - who has already helped their class team to score as many points as possible?  

 

Starter Activities

Practise your 7x table again - remember that we say the whole number sentence (1 x 7 is 7, 2 x 7 is 14 etc.) rather than just counting up and down in steps of 7! 

 

If you have access to a device connected to the internet, play ‘Hit the Button’ https://www.topmarks.co.uk/maths-games/hit-the-button   
Select the 7x table; play a couple of times, record your top score! Can you beat your score from earlier in the week?

 

Alternatively, if you don’t have access to a device, get your set of 7x table question cards.  Place them face down and see how quickly you can answer them in a random order.  Record your top time! Are you faster than your previous attempts?

LO: To find the perimeter of shapes

 

Today we’re going to be reminding ourselves how to measure the perimeter of shapes. 

 

Firstly, think back to your learning in Year 3...

What is perimeter?

 

Perimeter is the distance around the edge of a shape.  

 

If you imagine an ant walking round the edge of the shape, when the ant has walked around the whole of the shape and reaches the point which they started from then they’ve walked around the perimeter

 

Some people find it helpful to remember it as being

 

peRIMeter – the distance around the RIM of a shape

 

Have a look at my examples:

Picture 1
Picture 2
Picture 3

Now have a go at finding the perimeter of the shapes on the sheet below. 

 

Top Tip – each of the squares on my squared paper measures 1cm J

Plenary Task

Choose one or two of the rectangles that you've just worked out the perimeter for.

 

If the new scale was that one square of the maths book = 3cm, what would the new perimeters of these shapes be?
