My kindergarten teacher Ms. Valentino had certain non-sectarian pedagogical goals: She wanted us to learn to share, to respect our teachers, to obey our parents and to recognize letters, shapes and sounds. I think she did a fine job, and I look back on her small classroom in the annex of P.S. 42 quite fondly.
I especially loved show and tell. Once I brought in my teddy bear, and the next time my hamsters (a terrible experience it was when Mars got loose and was eaten by Mark Spindler's pet snake!).
