Last year was our first year using A4 colour coded copybooks with plastic covers and so far we are finding them great. Our 3 – 6 class use them and carry the copies forward from year to year so that they have continuity. This is particularly useful in 5 and 6th class and has the added advantage of less waste as the children. The colour coding makes the copies easily identifiable and easy to organise in the classroom. Highly recommend.
