\begin{enumerate}
	\item A tiling has been started below. The tiling pattern is created using a combination of the two tiles. The tiler continues to tile the floor by extending the pattern in the same way.
	
	Study the pattern, then extend it by drawing the correct tile in each of the 12 blank squares.
