There are a LOT of versions of the "Song Hospital" Review tool out there! This one from Primary Singing Ideas is my favorite. If you can't get permission to take up Sharing Time, then you could adapt it a bit to ONLY use the songs that need work - so they will all START in the Emergency Room and then need to be discharged. I will let one of the kids be the doctor - but the grading comes from me and the presidency - instead of bringing in another person.
Everything below is from Primary Singing Time Ideas HERE:
Before hand, I asked a brother in our ward to be our Doctor. I picked this brother in particular, because he has a background in music, which is helpful for "diagnosing" our primary.
I made this board from a tri-fold display bought at target. I spent WAY too much time drawing my "floating" hospital (I think I still need some lessons in art and drawing 2 dimensional figures...) So hopefully you can think of something MUCH simpler.
The inside is pretty boring. I ran out of time to decorate it more...which may be a good thing. :)
The inside says "Primary Song Hospital."
On each of the three sections, I taped the edges of a file folder together, and taped that on to each section. The sections were labeled "waiting room", "Emergency Room" and "Discharge".
I printed out forms for each of the songs, with a separate sheet for each verse. I was worried that we would run out of time. After having done it, I would recommend having one sheet per song, despite the number of verses. We weren't able to get through all of the songs.
I placed all of the sheets in the folder labeled "Waiting Room"
I did this on the 5th Sunday, on which I have the entire singing/sharing time for just singing.
I introduced our Doctor, outfitted with a white lab coat, stethoscope around his neck, and a clipboard. Then we had a volunteer "nurse" pick out a patient to be diagnosed. The nurse gave the paper to the Doctor, and we sang the song, then had the Dr. tell us our diagnosis. Our Doctor did a fantastic job in telling them "good news" and "bad news".
If the song got below a 4 in any category (words, smiles, watching chorister, melody, etc.) then it was sent to the emergency room. For Juniors, I'd pick an "ambulance driver" to drive the paper to the emergency room, and we all made siren noises.
If the song was discharged (meaning only 4 or 5's) then the entire primary received a squirt of "Miracle Spray". This is just lemon crystal light in a spray bottle. I told the kids to say "AHHH" if they wanted some, and if they didn't to just keep their mouths closed. THIS was a HUGE hit.
I wish we had been able to go through all the songs and then had time to work on getting the Emergency Room patients discharged...but maybe next time.
