Special Direct (TTS Group): This innovative clock is a really helpful visual aid for children who struggle to understand the concept of time passing, or how long 5, 10, 15 minutes is. There is only one hand and you move it to the start of either the blue (5 minutes), green (10 minutes), red (15 minutes) or white (30 minute) sections of the clock face. The clock will then keep actual time and the hand moves, so that children can see when their time is up for the task set.
