followed your post after your kind reply to mine
i very much sympathise with your concern, but would like to reassure you that i probably felt the same with my son when he was in reception. i felt he was ready for bigger challenges, but the emphasis in reception was very much about settling everyone emotionally and maybe bringing some of those who were struggling up to the base line.
for what it's worth, we just rolled with it through reception and the bigger challenges and acknowledgment of my son's needs did come pretty quickly in year one. so if i were in your position, from an academic perspective i wouldn't worry too much.... yet
having said that, it doesn't solve your problem of stopping your little one being bored throughout this year. maybe it has to do with expectations. i know in our house we all had expectations that learning would really kick off once he reached school whereas in reality it was another year til that happened.
could you explain to your little boy that he is really clever and you are proud of him for that, and in the coming months, maybe even next year, school will start to offer him challenges, but in the meantime give him permission to let himself just enjoy making new friends. or if he is quite goal oriented, maybe set him social/ emotional/ play challenges so that he can feel like he has succeeded/ is moving forward in some way?
as an example, i know my son is aware that a lot of his schoolfriends aren't at the same level as him and he genuinely seems to enjoy helping them, so maybe that could hold his interest? maybe explain his situation to him in terms of helping others - like if he is going over work he finds easy in school, like basic counting for example, he is helping some of the others to learn rather than learning it over and over for himself - my son loves to think of himself as a little teaching assistant it's not the right way to keep his relationship with his peers forever, but if it gets him through this few months with some motivation it might be worth it. your son sounds like a lovely, sensitive little soul, so i'm sure he'd like being kind to others...
hope we can help each other in future xxx
