In reception last year the ta took out all letters and looked in contact book yesterday when ds came home his dinner money was still in his bookbag surely he's a bit young to hand it in himself and arent they meant to look in his contact book??!
At my son's school all the reception children are trained to take everything out of their bags - letters, water bottle and lunch money, and put them in the right places. I was concerned that slightly ditzy ds would never get the hang of it, but a few weeks in and he was completely independent.
I would expect Y1 children to be able to do it themselves, but would also expect school to help them get the routine sorted. Maybe that's what happens in Y1 at your school, but the system isn't in place yet. I would ask what the expectation is this morning, explaining about the money, then you and school can help reminding him what to do.
