LOGO CHALLENGE is a computer program for children. It has been designed to promote problem solving and logical thinking and can be used with pupils from a wide range of age and ability levels. The program is aimed at children of average or above average ability with ages between nine and thirteen years, but also can be used by younger children with guidance.

Through LOGO CHALLENGE, children are introduced to the logical problem-solving skills involved with programming a computer. The child's role is to command a 'screen pen' to draw pictures or patterns. At first these may be simple shapes such as squares or triangles. Later these basic elements can be combined to produce complex and fascinating constructions.

Even at the simplest level there is a need for clear thinking and logical analysis. Only a carefully thought out and precise series of instructions will produce the required result. Anything else will result in a flaw in the picture or a 'bug' in the program. The appearance of such a bug presents the learner with a challenge to find and correct the error.
