Easy to learn and teach: This is a professional wall clock designed for children's learning. Each quarter is color-coded, helping kids easily understand terms like "o'clock," "quarter past," "half past," and "quarter to." The 5-minute increments around the outer edge further assist in learning how to tell time. Early development: This clock was created to support parents teaching their children how to read time. The design is simple and intuitive, with color-coded quarters to help children quickly associate numbers with their positions on the clock face. Research indicates that colors can positively influence a child's mood and learning. Every detail of this clock is optimized to enhance learning effectiveness. Silent sweep movement: This children's analog wall clock features a durable construction and silent sweep movement, eliminating the distracting ticking sound. The quiet operation makes it ideal for bedrooms, nurseries, and classrooms, helping maintain a calm and focused environment. Long battery life: Powered by a single AA battery (not included), the low-power quartz movement ensures reliable performance. For best results, use a standard carbon battery to maximize battery life and time accuracy.
