Open up children's STEAM thinking, and cultivate children's ability to use their brains to think and solve problems by stacking building blocks and creating splicing tracks. All kinds of brightly colored tracks, building blocks and rolling balls, to establish basic cognition of color, shape, size and so on. Explore the mechanics of rolling balls and the idea of ​​splicing multi-style tracks to train the sense of space and creativity Included are 102 parts, 10 rolling balls, and advanced assembly learning instructions, leading children to understand the causal relationship from plane to three-dimensional, front-to-back order, slope height, and spatial structure from construction. Children can develop more changes and creativity, use imagination and creativity to build more styles of building block construction and rolling ball track connection methods. Through the rolling ball track, train children to observe the path of the rolling ball, train their visual tracking ability and think about the design direction of the rolling ball track. Encourage children to think independently, and they can also be creatively constructed by multiple people. During the assembly process, children can train patience and learn teamwork, communication and coordination. According to the difficulty level, various assembly methods can be distinguished to create bouncing tracks and stunt tracks, adding more fun and challenges. You can also purchase other extended theme track sets to make learning more diverse, rich and interesting, and create your own track kingdom for children.
