Compound Shapes (rectangular)

A very basic worksheet that I use to find area and perimeters of compound shapes made from rectangular shapes.
I give them to the students and ask them to write down some information they know from the diagrams - it is never long until the whole class is finding the missing sides, at which point we stop and discuss how this is done (and at this point I usually have to give out highlighters so they can colour the horizontal and vertical lengths different colours).
Once this is done we then discuss how to calculate the perimeter and students do this for all the shapes on the sheet (I get them to do this in their book).
We then look at how to calculate the areas, and again students record their working out in their book (although they show the ‘splitting up’ of the shapes on the sheet).
Depending on how students have done on this I may introduce different shapes before ending with a nice Exit Card on what they’ve understood.
