Morphun LeversSThese are the blocks whose main purpose is educational child labor and its multifaceted development. With them, the child has the task of constructing levers and swings so that they remain in equilibrium. With this exercise, the learner learns to fine-tune the individual elements with particular attention to the whole structure. And this, as in the case of projects of this type, is very unstable. Besides, during play, the child must show patience as not every attempt is successful. At the child's disposal, 24 work cards are required to complete 21 exercises.
