History of Tangram

The tangram is a dissection puzzle originating from China. It consists of seven flat pieces called tans, which are put together to form a square. The objective is to rearrange the tans to form various shapes. Although the exact origins are unclear, it is believed that the tangram was invented in China during the Song Dynasty (960–1279). It gained popularity during the 19th century when it was brought to Europe by traders and missionaries.

In Europe and America, tangram became a fashionable pastime, appearing in various books and games. It was often seen as both a form of entertainment and a tool for education. Despite its ancient origins, the tangram puzzle has remained relevant through the centuries, seeing adaptations in modern educational programs and digital formats. Today, it continues to be popular worldwide, serving both recreational and educational purposes.

Educational Benefits of Tangram

Tangram puzzles are widely used as an educational tool for children and adults alike. They offer a hands-on approach to exploring geometric terms, such as rotation, symmetry, and congruence. By manipulating the seven tans to fit into different shapes, players gain a better understanding of spatial relationships and problem-solving skills. This experiential learning can help solidify mathematical concepts, making them more relatable and easier to understand.

In addition to enhancing mathematical skills, tangrams also help in developing other important competencies. These include fine motor skills, as manipulating the small pieces requires precision and control. Moreover, tangrams can aid in improving concentration and patience, as solving the puzzles often requires focus and iterative attempts. For these reasons, tangrams are frequently included in classroom settings and educational curricula.
