A jigsaw to help revise perimeter and shapes.

Some students find it incredibly difficult to visualise nets being folded up into 3 dimensional shapes. The best way to gain confidence with this is having fun making lots of different shapes and I have already blogged about an excellent site for this where you can print off all sorts of nets and make some amazing shapes. With exams rapidly approaching you may not have time for that so here is a page from Nrich where you can watch 24 different nets being folded up to make 3d shapes. Before you press play each time try to work out what the shape will look like when it is folded, then see if you were right.

Do you know all the important words for shape? This is a simple matching game to help you. Each time you play you will get a different selection of words.

When I was a newly qualified teacher in the early 1980’s the latest trend in maths teaching was Logo. We used to get the students programming the BBC computers to make amazing patterns and shapes. We even used to have a little turtle robot that you could program to draw shapes on the floor! You can have a go at Logo here thanks to Transum.
