You can extend the learning by singing about things in your home or classroom: Have fun swapping household items or furniture for “hat” in the song, for example, “My table, it has 4 legs, 4 legs, has my table, and had it not 4 legs, it would not be my table.” (My pants, they have 2 legs...., my car, it has 4 wheels, etc.)
