It's time to get all the boxes out and try to sort them into types depending on their shape. Much can be done at home to help with 3-D shape work and children love to play with empty boxes; the bigger the better. It's well worth collecting a store of boxes and much discussion can take place about them, including mathematical language of sides, edges etc. These four pages look at matching shapes and finding the odd one out and would work really well at the same time as looking at real 3-D boxes. Don't forget to look at the rest of our Shape and Measures pages which can be found tucked away in the Further Resources section. If you haven't already got our 3 day trial then now's the time.
