Modelling teaches kids patience. It teaches them tolerance. It also allows them to expand their knowledge and appreciation for art in all it's forms. The skills involved in modelling develops a child's dexterity, their spatial awareness, 3-dimensional cognitive processes, ability to visualise and plan, and most importantly, evolves their problem-solving skills.
Modeling is an artistic process that unleashes ones creativity, imagination, and even their mathematical powers! When I see a child show a keen interest in modeling it brings a happy tear to my eye. Not because I have found a new kindred spirit, but because I see the immense potential in that one child's eyes, and the wonderful life they are destined to live!
Don't under-estimate the power of modelling!
