Each child is given a game board with boxes to mark and a set of pirate coins, in a place visible to all players should be placed tokens with letters (tokens should be cut out, folded in half  along the dotted line and glue) in such a way that the letters are invisible. 

Game flow:

The instructor reveals one token each with a letter, children find the letter on their board, if the letter is on the board - the child covers it with a coin. The game continues until the first child covers all the boxes (thus winning the pirate treasure) or until all children cover their boxes.

Variant:

Instead of the pirate coins included in the set for when you can use real coins.
