For Music leader. All the songs for the year that are picked to match each monthly theme. and a copy of Bdays for the Primary. Just so she is prepared with a song for bdays. My Music leader is very organized and has her own weekly planner and monthly planner for herself and for the Primary Pianist.
I don't usually make a binder for the pianist, but I do give her copies of the music that are not in the Children's songbook.
Teachers receive in a 3 ring binder, manual, pictures assigned to manual. Class lists with address, phone numbers and birthdays of students. They also get a list of assigned lessons for the year. I used the lesson schedule maker on LDS.org and put in Stake Conf, Gen Conf, and program practices and the assigned lessons for Easter and Christmas. I try to include useful tips to fill remaining time, a letter to the teachers with procedures and duties. Presidency names, phone numbers and emails. Sub lists are updated quarterly. I include a list of songs for the year as well. We usually invite the teachers to stay after the block for 10 to 15 minutes to give out binders, and explain the challenge for next year. We provide a small refreshment like cookies or fruit and answer questions. Usually on the last Sunday of the year.
