D.,
My son is 5 also and started Young 5's this year. What you are describing sounds typical of what I have been observing in his classroom. The Young 5's program at his school is an all day program, but they only go Mon-Wed-every other Friday. I have been helping in his classroom almost every day he has had school (he has had 4 school days) so far this year.
What they are working on is staying in your seat, or staying seated if everyone is sitting on the floor. Walking in single file lines and keeping quiet when in the halls. Lunchroom behavior, and ordering hot lunch (making a choice between 4 different entrees) or cold lunch. Raising your hand when you need help, or want to answer a question. Routines and rules, and learning whats expected of them are the biggest things they are focusing on right now.
All the rules and expectations can be a bit overwhelming for them. There have been many tempers and tears already, just today there were 5 children who lost 3 minutes of "playtime" because they repeatedly would not listen or follow directions. They cried and carried on, and were very dramatic (mine included I'm sorry to say), but they have to learn appropriate behavior and whats expected of them at school. I know they must master this if they want to be successful in school.
I also have a son who started First Grade this year, (he was in Kindergarden last year, and I helped in his class also) Kindergarden was a totally different experience. They expect a lot more from the children in Kindergarden, as they have so many more expectations academically to accomplish over the year (too many if you want my opinion, but I don't set the curriculum) so in Kindergarden they don't always have the luxury of time to cover these basic things. By the end of Kindergarden, they are expected to read and write basic sentences, count to 100 by 1's, and 5's and count to 20 by 2's, and thats just the tip of the iceberg.
If your school offers a Young 5's program I would suggest that you take advantage of it. Give your son that extra year, not only to learn some of these things in a slower paced environment, but also to give him an extra year to mature. I personally believe that boys should be at least 6 before they start school because they aren't ready to sit still for that long.
I wouldn't necessarily punish your son, if hes just not ready its really not his fault. You can talk to him about how important it is that he do what the teacher asks and that he be a good listener.
I also have older children and have a 7th Grader that struggles in school and I really wish a Young 5's program would have been offered to us when he was just starting out. Anything that makes the school experience more positive and successful for the kids, in my opinion is well worth it. Good luck to you and your son and I hoped this helped.
