Well.. after a week now, I can say that I was wrong. On the teaching front at least.
The first three days was mostly observation of the teacher and how they teach different lessons and subjects. I was involved with some small group activities, such as reading groups - the children take turns reading a book, then if they get it finished, the teacher/teacher aide/me then collects up all the books and tests them on their knowledge of what happened during the book. Then if there are any words they don't know, they write them down in their books and use a dictionary to look up the meaning. Another small group was spelling groups, where I took a few kids and went through a few worksheets that had words using particular vowels/consonants.
On Wednesday and Thursday during particular lessons, I took individual kids out for a few minutes to test them on their counting abilities (counting backwards by two's, counting upwards and backwards by 5's and counting upwards and backwards by hundreds) and then writing down any problems they may have had while counting. Some kids did a lot better than others did, but for those that had trouble, I did try to prompt them until they got the next number.
The class I have are all pretty well behaved. Some of them do muck up sometimes and so you have to go over to them and talk to them or tell them to sit in their seat or for them to be quiet, but apart from that, they're good. Some of them talk to me more than others do, mostly the boys, but there is one girl who, in the first couple of days, would stare at me until I looked at her and smiled at her, which caused her to smile and turn back around, or I had to tell her to turn around. There are still times when she does that, but it's not quite as often now. But my gosh, year 2's are pretty cute! I'm so glad I got that year level for my first prac!
I now have one more week of prac left, in which I have to teach three lessons - one on Monday, one on Tuesday and one Wednesday. I know it's probably because it's a novelty to me, being with a younger grade, but I do look forward to seeing them each day.
