Each child receives a set of planets and a board with places for collecting planets. Lay out the cards with the planets turned upside down in a visible place. Each of the children turns one of the planet cards in turn and places the same planet on the board, then turns the planet card back upside down. If, in the next move, the child discovers a planet card that he already has on his board – he loses the queue. The child’s task is to collect all the planets on the board.
