It is very important to children to develop assiduity and attention from early age. It is the simplest to make it in a game form. For example, playing game "Find couple! For children". In this game for children it is necessary to look for identical couples of cards, opening them on two. At the same time if couple did not coincide, then cards are closed, and the kid needed to remember what cards there. But it is not difficult at all as in game there are different levels of complexity. It will be easy for kids to pass level 2 on 2 or 2 on 3 cards, and to children is more senior 3 on 4 or 4 on 5 cards, there are levels more difficult – 5 on 6 and 5 on 8. Also, in game there are 4 sections: fruit and berries, insects, vegetables and animals. Players can independently choose that section which most of all will be pleasant to them. Kids always like to set up new records, for this purpose we provided time timer. Playing such game, the child will learn to compare objects, to allocate the main signs. Will consolidate the concepts "different", "identical" and "steam". Well and, of course, game well develops thinking, memory and attention.
