Learning to assemble animals building blocks itself is a combination of play and learning, allowing children to learn without knowing it, so that they will not have a rebellious attitude towards learning, and children can easily learn knowledge inside and outside of books. It can better develop children's personality. During the construction of animals building blocks, children need to use their super imagination and free play. Persistence for a long time can cultivate children's personality. Children are natural learners, but children don't like to be forced to learn difficult or too easy knowledge. In the process of "playing", it will be easier for children to explore and discover the world that belongs to them, whether in books or outside of textbooks. I believe that children's self-confidence can be enhanced through hands-on practice, even if they fail, at least try. In this way, it will be easier and eager for children to master various knowledge in books or extracurricular. And it will be easier for them to remember this knowledge.
