Maths

 This week we are going to be learning about perimeter. Perimeter is the distance around the outside of a 2D object. It is usually measured in millimetres, centimetres and metres.

  To find the perimeter you need to:

  1. Find the length of all the sides.
  2. Add all the sides together.

Have a look at the websites and videos below to find out more about perimeter:

  Activity 1:  

I have allocated you an activity on MyMaths called introducing perimeter. Have a try of this to help you learn  how to find the perimeter. Remember to find the perimeter you need to:

  1. Find the length of all the sides.
  2. Add all the sides together.

Activity 2:

  Have a look at pages 78 and 79 in your target your maths book. The answers are below. Remember to check your answers and look back at the question if you find a mistake.

Activity 3:

  Have a look at lesson 9 from our power maths book below.

Remember to find the perimeter:

  1. Find the length of all the sides.
  2. Add them together to find the perimeter.

Therefore, if we know the perimeter but don’t know the length of one of the sides we can:

  1. Find the total of the length of the sides we know.
  2. Subtract the lengths we know from the perimeter to find the length we don’t know.

  Extension 1:  Have a look at MyMaths, I have allocated you two tasks about division to keep your skills sharp! Have a look at ‘bar division’ and ‘dividing’.

Extension 2: Practice your times tables. You could play one of the games below, spend some time on TTRockstars or have a look at some of the times tables songs/ dances I’ve found below:
