Hi. I guess it depends on the school, but both of my boys are very happy and relaxed at school. I have a Year 3 and Reception child. From what they tell me, and what I have seen, a typical Year 1 day involves:
Parents drop off, usually at door with Year 1. Children sort out coats etc, and sit on carpet for Register. I am told that they do Literacy and Numeracy in the morning, along with Phonics. They sometimes work in groups, particularly for these subjects - it all seems quite relaxed. School send out details of the curriculum each term, and you can see that they work through various topics. They may study "Instructions", or poems etc.
They have a break with a snack and drink mid morning, and play in the playground. Lunch is just after 12 noon for the infants, and they have another break mid afternoon.
In the afternoon, they do other subjects, including topic work eg. Castles, in which they incorporate Art, History, Geography, Music. Oh, and PE twice a week, computer work, Assembly, and odd days when the whole school covers a topic like Art, or Sport.
If you get offered a place, make sure you have a good look around and get feel for the school. I help out at ours when I can, and I do find it to be a very warm and friendly place.
