Can't get "Let it Go" from Disney's Frozen out of your head? Do your students sing it constantly, and you always think to yourself, how can I use this to my teaching advantage? I have come up with the perfect solution! I changed the lyrics of "Let it Go" to an original song entitled "Let it Grow" which focuses on living things and plants. My pre-kindergarten students loved learning this song and performing it for a music video which brought down the house at school!
