It comes with a comprehensive teacher's guide that allows for hands-on, inquiry-based exploration where children can see real world examples of science concepts in action. Help your students develop a better understanding of STEAM (science, technology, engineering, arts, and math) subjects with this toy. As they click the parts together, they'll strengthen their hand-eye coordination, fine motor and problem-solving skills, and spatial awareness. Studies reveal that students experience more success learning STEAM subjects through activities related to the real world than by reading about concepts in textbooks. K'NEX Education sets allow students to build replicas of machines and contraptions, and through the lesson plans and experiments, to gain a concrete understanding of the principles that make them work.
