The brucco tree, which brings together professors from harvard university, zhejiang university, and based on the montessori sensitive period theory, as well as the classic piager cognitive development phase theory, combines brain science research, etc., proposes the key strength of brucÓn growth and is committed to a more scientific approach to providing more suitable wood products for children. There are three components of the bruco large particle building system: round-tune particle particle pyramid, soft rubber pyramid and science-technology pyramid. The science-based interactive building blocks cover a variety of interactive functions, such as electronic mobility, acoustic light, sensors, programming, and ap connectivity, so that the building blocks can interact with children in a simple way. The addition of technological elements has allowed the breco particle blocks to subvert the experience of the use of traditional blocks, making them more fun to spell; to see, move,...
