Here is a brief list of my favorite memories with each group along with an explanation of why they are special to me:
1) Science lessons in the laboratory with 1A, 1A is a very large group, and getting to work with them in the smaller space of the laboratory allowed me to interact with them and get to know them more easily. No particular moments stand out, but these lessons would have a special atmosphere that combined the relaxation and playfulness with attentiveness and effort.
2) Music with 2A--2A is group that has a lot of chemistry, and this was most visible in music classes. Rehearsing "I Saw Mommy Kissing Santa Claus" for the Christmas concert is one of my favorite memories, as well as singing "YMCA", by the Village People, with the boys at the end of the year.
3) Biology with 3A--3A is a group with a high level of curiosity, and, as such, I enjoyed myself with the group a lot in biology and social sciences. Biology comes to mind because, in explaining the biological definitions of words, we would oftentimes go on interesting tangents on the broader concept of the words, as well as any colloquial usage they might have. They were classes that combined the academic with the everyday.
4) English/Spanish exchanges with the teachers--Everybody on the bilingual staff was highly interested in honing their English, both formal and informal. My favorite moments were exchanging informal expressions in English and Spanish.
