Self Control for Preschoolers

In my Imagine That! class one little girl is learning self control in order to respect others and she is truly inspiring! A 4 year old girl in my class has had this habit of talking while I or others are talking or singing. She started doing this once she got comfortable in the class atmosphere (after about 3 classes). I explained to the class at large that when Miss Tandy or a student is talking, we must learn to be good listeners because what we have to say is important. I further explained that we must respect one another and not interrupt. In the case of my singing, I explained, they had 2 choices: 1)sing with me or 2) be a good listener but "It is very difficult for Miss Tandy to sing when you are talking". I said this first about 4 weeks ago (we meet once weekly) and every week thereafter because it was very necessary for her to be reminded! She had a very difficult time with this form of self control until this week! Something happened and she has been the most respectful, best listener and singer in the whole class! As my classes are PROCESS not PERFORMANCE oriented, I didn't tell her that she is the BEST listener, but I told her: "You were very respectful today of Miss Tandy and the other students and I am soooooo PROUD of you!!" And I certainly AM!!
