What are the principles you must take into consideration in designing the practical life materials?

When designing practical life materials, it's essential to consider the child's developmental stage, ensuring that the activities are age-appropriate and promote independence. Materials should be aesthetically pleasing and made from natural, durable materials to engage the child's senses and encourage exploration. Additionally, activities should support fine motor skills and coordination while allowing for repetition and mastery. Finally, the setup should foster a sense of order and organization, facilitating a smooth transition between activities.
