Building block is a kind of children's toy, but its design and significance go far beyond this. The components contained in building blocks refer to various small objects such as building blocks, sticks and wheels. By combining, assembling and stacking, they can be freely spliced into various shapes, so that children can exercise their thinking ability and creativity in play.

The number and types of components contained in building blocks are different, which can meet the needs of children of different ages. Early building blocks were mainly simple wooden blocks, but with the progress of science and technology, building blocks gradually covered high-tech elements such as electrical components, sensors and programmers, which brought more creative space to children.

The design concept of building blocks and its inspiration to children are getting deeper and deeper. Nowadays, some building block brands have incorporated the STEM education concept into their designs, and helped children to establish innovative thinking and problem-solving ability by guiding them to learn knowledge such as science and technology, engineering and mathematics, which has become an important recommended teaching aid for educational institutions in many countries. Therefore, the components contained in building blocks are not only simple toys, but also form a unique educational way and concept.
