This set of robust beechwood sand timers is a great tool for visualizing time for children in preschool, kindergarten, and elementary school. Watching the sand fall, children playfully train their sense of time. It's ideal for when they brush their teeth, do their homework, cook, or need to keep track of time while reading or playing. With a length of 14 cm, the sand timer is easy for small hands to grasp! Watch time fly! This set of sand timers with durations of 1, 3, 10, and 30 minutes trains an understanding of time and duration and also makes a great visual impression with its high amount of wood material combined with modern colors. It's an eye-catcher in the classroom or children's room. Particularly pleasant haptics with rounded shapes.
