This unit is designed to acquaint elementary students with the way a computer operates and the way people communicate with computers. The format of the unit was designed so that the instruction can be provided by the classroom teacher. The lessons are constructed so that, with some teacher guidance, the students can work through them step by step. Follow-up activities for each lesson provide students with an opportunity to apply what they have learned in the lesson sequence. Challenge assignments provide additional stimulation for students who learn the language more quickly than others. Included in this document are parts one and two of the "Starting Apple LOGO" program and 15 task cards. The program includes five lessons and two sets of supplementary activities. (CW)
