The construction set consists of 112 parts, from which you can assemble 5 models: an airplane, an ATV, a chair, a scooter and a mill. We recommend using the construction set both for home use and for group classes in kindergartens (from 5 years old) and in elementary grades. Playing with a metal construction set helps develop logical thinking, spatial representation and observation, and creating your own models is the basis for developing a child's creative thinking.
