This a 6 page document with 1 rule for each letter in the word 'MUSIC'. The 6th page has all the rules listed on 1 page so you can print them off on one page if you prefer. I my early years area I have the 5 posters up, and in the elementary/older primary I just have the 1 poster with all the rules listed.

They are bright addition to your classroom and a great visual reminder to the students of what is acceptable. Enjoy!
