Time after time, experience shows that learning by manipulating physical objects with one’s own hands — learning by doing things firsthand, rather than being told about them or reading about them in a book — is extremely effective. Thames & Kosmos has a long history of incorporating this principle into science education. Now, they are bringing this experience to the Kids First Math line, a series of nine hands-on kits with activity cards or lesson guides designed to demonstrate and teach concepts in mathematics, as well as other skills such as logical thinking, problem solving, and creative thinking.
