Kids learning games teach through play, using projected pictures, touch screens and sensors. Topics include counting, drawing, animals, building and science. Nurseries, primary schools, libraries, science centres and play centres buy them to give children a hands-on activity. When choosing, match the game to the age group, decide between a floor, wall or table set-up, and think about how many children play at once. Classroom packages suit a teacher who wants set lessons, and standalone games suit drop-in visitors.
