There are a lot of holidays in the year, some large, memorable, and a whole bunch of professional ones that are remembered by those to whom they relate. There is such a holiday as Children's Day. It was approved in 1949 in Paris and since 1950 it has been celebrated on the first of June of each year. This Day should remind adults that children also have rights: freedom of education, opinion, life and protection against violence. We also decided in our own way to celebrate this holiday and offer you the game Children's Day Differences. In it you must find the differences between the pictures of the children.
