Excel Compound Areas and Perimeter Activities

Reusable mixed ability spreadsheets for Excel / Open Office covering skills involved with finding simple and compound perimeters and areas; involves finding perimeters and areas of overlapping lines that form a rectangle within two rectangles; uses technical terms such as congruent and bisect, etc.; worksheet and I.W.B. versions. I.W.B. versions with working models to help children see how what happens elsewhere within the shape effects other parameters in ‘real time’. All sheets can be reused time and again with the press of the F9 key to generate new numbers with answers (can be displayed on I.W.B. for self-marking and repeated demonstration) and print to A4 to allow as much practice as required with additional sheets for lessons or extra homework practice. Whilst using this resource with a Year 6 class one boy said to me he hadn’t understand this but now he did and two Year 6 teachers in another school told me they had used the files “quite a lot”.
