External Perimeter

In year 4 maths Ms Patels group have been learning about perimeter and we have seen that it is the outside of the shape that the perimeter.
We will be finding the perimeter of all Glade primary school and see how big the school actually is! But we are going to count the number of external walls. To find the perimeter of a given shape you must add up all the sides to give you the correct answer.
