The Ebury cassettes I've seen have kept up a consistently high standard both in the programming and in the packaging and documentation.

The first game concerns comparisons of size. It is meant for one child who simply operates the space bar. Two objects are shown, one of which changes size. The idea is to stop when they are the same.

The graphics are good, with a variety of items like ice-cream cones, trains, bottles and so on.

The second menu offers three variations on the theme of Climbing and Growing. Animals on a step have to be made taller or shorter with single keys to fit within a given space.

The second stage involves placing the animals higher or lower on the steps to accommodate their size. The final part combines all of these decisions.

Both programs provide the sort of repetition needed by young children to reinforce basic skills in a colourful and imaginative way. There were plenty of suggestions for extending the ideas in the Parents' Handbook.

The children enjoyed playing the games and found no difficulty in operating them.
