David, My experience was when I was student teaching. I had always taught in special ed and alternative classes, mainly middle and high school. I was called to sub in a fifth grade . When I got to the school, they put me in a kindergarten class. I immediately wrote my expectations onthe board in cursive, pulled out books for silent reading and waited happily for the students. Then I remembered it was Kindergarten and they could not read the board or the books. I had a great day!! One child covered his face with paste and I had to peel it off, one student said a bad word and I corrected her sternly, she cried, then they all cried. Bathroom duty was constant "Helping".
All in all, it was the worst and best day of my life. I taught the class for a week and on the last day, the girl who cried gave me a hug and aske d me to stay. Needless to say, I specified the groups I wanted after that, but Ihave never forgotten the look on the children's faces when they saw all that writing on the board LOL
