Tidy and Sort
This resource provides an opportunity for children to investigate a variety of ‘mixtures’ and the means by which they are best separated. The activities are put in context using a storybook, in which two sisters are presented with tubs of mixed objects to sort out. One of the sisters always wants to find the easiest way to sort the objects, and the other sister begins to use the same approach.
This resource is now available to purchase through the University of York's Online Store.
