Very young children have not yet developed the ability to build a three-dimensional space model, but the magnetic force of the magnetic sheet itself will make 1-2-year-old babies feel magical. By grasping and releasing, they can exercise their hand coordination ability well, and also let the baby feel the color and shape. A 2-year-old baby can choose to piece together some simple patterns, such as two triangles to make a square or a simple three-dimensional pattern. Babies aged 3-5 can piece together simple three-dimensional patterns, cubes, spheres, triangular cones or three-dimensional animals, cars and other complex graphics. Children over 6 years old have higher requirements for magnetic puzzle. They can piece together their imaginary patterns according to their imagination and creativity, such as cars, crabs, ferris wheel and so on. Of course, children will be more creative if they are accompanied by their parents.
