I would have, (depending what time it was), called the Teacher at school, tell her his homework packet is lost. I assume, the homework packet thus has his name/classroom number/Teacher's name on it.
And give her a head's up.
AND tell the school/Teacher, that his sweatshirt and Karate glove, is lost, too.
HOPEFULLY his items has his NAME on it.
My kids' school has a HUGE BIN of kids' stuff that is lost or forgotten daily. But the items don't have names on it. So it is tossed by the school because it goes unclaimed.
He is 6. My son is 6 and in 1st grade too.
If that happened with my son, I would have, written a note to the teacher, put it in my son's backpack and tell him to give it to the Teacher tomorrow morning. BUT I would have, also.... e-mailed the Teacher about it.
And I have done that, when my son had, forgotten or lost something at school.
My boy is 6. He is really good about things, but there is a HUGE margin of error, in kids this age and being a boy. Common. They forget things or misplace it. It happens everyday.
I don't "punish" my son for that. Because... he did NOT do it, on purpose. It was an honest mistake. And the Teacher knows him and knows he is not like that, everyday. She doesn't punish him over it, either.
Even I, forgot my grocery list once and didn't know where I put it... and I was already AT the grocery store to grocery shop. I did not punish myself.
You need to, send a note with your son, in his backpack, for the Teacher tomorrow. Or yes, you go and take your son to school tomorrow.
Or, isn't the Teacher able to be contacted by E-mail? That is how many teachers do things nowadays.
Tell your son, to give the note to his Teacher tomorrow.
Explain, that he forgot or lost, his homework packet/his Karate glove and Sweatshirt.
But if these things do not have his name on it, then there is no guarantee it will be found. Hopefully it is all just there in his classroom still.
I wouldn't punish my son about this.
My son HAS forgotten to bring stuff home from class before. But it is not habitual. It was honestly forgetting. He and his teacher and, I... know that.
And it did not... snowball into a mess.
