We are riding in toy cars

The set consists of 6 cubes measuring 4x4 cm. The child needs to assemble the image from 6 fragments. As a hint, 6 pictures of land transport are provided. The picture is placed at the bottom of the box, and... the child places the required cubes on it. During the game, the concepts of "part" and "whole" are introduced, and the ability to work from a sample is developed. The stickers on the cubes are made from high-quality smooth paper that does not get damaged during play.
 
And there's a surprise for the little one! If you assemble the picture and turn over all the cubes, another picture will appear.
