In the first step the clear tray (controller) is placed over the book. Each of the squares in the book has a small symbol in the upper left-hand corner. The tile with the matching symbol is placed over the square.
In the second step the first tile - the one with a house - is lifted up revealing the symbol underneath. The house tile is placed on the matching symbol in the lower half of the book. This is repeated for each tile.
In the third step the controller is closed by folding the top half down on to the bottom half. The controller is then turned over revealing the pattern on the back. This is matched to the pattern in the lower left-hand corner of the book. The patterns will match if the problems were done correctly.
