Make Every Minute CountLearning Center Classroom Sets are the very same 8" Original Time Timer that teachers and kids have grown to know and trust since 1994. When the colored disk is gone, time is up, helping children to self-regulate and teachers or caregivers to better manage both time and task in the classroom or clinic setting! Each set comes with three timers of different colors (with a protective lens) to aid in color curriculum in the early years and for time management in color-coded classrooms. Silent operation with optional audible alert at end of timing Magnetic back and fold-up feet Supports kids with ADHD, sensory integration disorder or autism Age 4+ Ideas for Use: Use when completing class assignments to get a sense of how much time is left for that activity Use during classroom center time to let each group know when it is time to move to the next center Use in a therapeutic setting to help a child know how long the session will last
