The purpose of this study was to teach the parts of an inch in sixteenths, using a constant time delay procedure. Constant time delay is a virtually effortless, or near errorless, instructional process involving the simultaneous delivery of a target stimulus and a controlling prompt for a limited number of trials, followed by trials where the target stimulus is presented, but the controlling prompt is delayed for a constant time period. The study was conducted with 6 sixth-grade students in a self­ contained math class for students with learning disabilities. The subject group contained 5 males and 1 female. Each of the 6 sessions began with a group choral response to the stimuli with a zero-second delay. Next, three trials, with individual subject responses, were conducted with a three-second time delay.
