Here are a couple more gap fill options related to the song ...
I also recommend playing LastOneStanding - the musical listening game. Put up these words on the board or show this image.
Students write one word BIG on a sheet of paper and stand up and hold it up (or groups can choose one word and play together as a team). Play the song and as students hear their word, they sit. Hear it again stand and so on. Lastone or team standing wins!
