We get about 5-10 minutes each. I have only been to one though as dd has just joined year 1.
All I asked (whilst looking through a folder of dd's work that teacher had put together) was...
1. Has she settled in well? 2. Does she play / interact nicely with the other children? 3. Does she behave herself in class?
This year I will be asking the above plus questioning how the teacher feels she is progressing academically with reading, maths etc and if there is anything she needs to practice a little more at home.
