This set includes one 13" demonstration clock and 24 smaller 4" student clocks, all with synchronized hour and minute hands for teaching time-telling skills. The group-friendly design allows instructors to demonstrate concepts on the large clock while students practice simultaneously on their individual clocks. The clocks feature a yellow face with bold black numbers and contrasting blue (hour) and red (minute) hands, matching common textbook illustrations for clear visual reference. Made from durable plastic with geared mechanics, these clocks are designed to withstand regular classroom use. The set comes with an activity guide containing games and exercises suitable for learners ages 5+, including kindergarten through elementary grades and ESL instruction.
