WALT: calculate the perimeter of polygons.


Following on from yesterday's work on perimeter, today you will be calculating the perimeter of some basic polygons.


A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). They can have any number of sides but a shape with curved sides is not a polygon.


You can re-watch the video from yesterday, on if you want to go back over what you have learned as well as looking at a very short powerpoint if you need to which can be found in Resources.


Please choose the relevant numbered challenge to complete.  Once you understand how to calculate the perimeter, you will find the challenges quite straightforward.  If you find the challenge on which you start too easy, please try the next one up as there are not many questions in each challenge.


There are also 2 extension challenges, one of which has worded problems for you to attempt as well as missing lengths.  We will cover missing lengths tomorrow but don't be afraid to have a go!
