Children's glass water cup: Dimensions 4*5.2*5.5 cm. Specifically designed for Montessori's self-prepared food drinking process. It helps develop hand-eye coordination and self-care skills through the process of pouring water independently and drinking with the cup Safety Operating Procedures: The edges of the glass are smooth and rounded. However, adults must clearly demonstrate the steps of "holding the cup with both hands - sipping the water - placing it back in its original position" and supervise the entire process to prevent the glass from breaking and causing injury Fine motor skills and hand-eye coordination: Guide children to grasp a small cup and pour water from a water bottle, control the flow rate and balance the cup, and exercise wrist strength, hand-eye coordination, and the ability to work hands together Life skills and independence: Participate in the actual water-drinking process (taking a cup - pouring water - drinking - cleaning), cultivate self-service awareness and responsibility, laying the foundation for independent eating Concentration and Order: Repeated operations can enhance patience and concentration; Store water bottles in fixed positions to strengthen the habit of organizing items, recommended for professional Montessori families or kindergartens
