I am so cross with ds2. He told me he'd checked and there wasn't anything he needed to do to catch up from missing Monday. He also said all the homework was on the school's virtual learning site, except maths, but that the teacher had explained that and he knew what he had to do. (This was yesterday afternoon.)
This evening he tried to do his French homework and his logon for the external website they're using wouldn't work. Then he told me that during yesterday's lesson quite a few pupils said they couldn't log on, so the teacher took their names and said he'd sort it out. Ds said he didn't know his logon wouldn't work at that point, because he was away on Monday when the homework was set and he didn't think the teacher realised he'd been off sick.
Then he told me that he can't do the maths either, because he doesn't have the questions and thinks the class must have been given a worksheet when he wasn't there on Monday. So he hadn't been to speak to his teachers about catching up at all.
So, he hadn't been to speak to his teachers about catching up at all and he clearly didn't know what he was doing with his maths either. 
He's being all sad faced and teary with me, because I got cross about it. We talked about the importance of him showing the initiative to go and speak to the teachers and actively catch up what he'd missed and he said he would, but then he clearly didn't bother. I doubt either teacher is going to be impressed that he didn't approach them about being off on Monday and that's if he manages to get hold of them, as he says he doesn't know how or where and there isn't any time.
If he doesn't get hold of his Maths teacher he will undoubtedly get a detention for not doing his homework, as it's due on Friday and he won't be able to do it. Unfortunately they were put into sets last Friday and he none of his close friendship group are in the same set, so we can't even text anyone to ask for the questions or where to find them.
To cap it all, we're busy all weekend and he's put off some homework that's due Monday and Tuesday, when he won't have time to do it over the weekend. He was fully aware of this at the beginning of the week and promised to get it all done on the nights it's set.
So after all that, he then looked at me and said "Can I have computer time now." 
I give up. Perhaps he needs to be given a detention to wake him up.
I know he's tired and under the weather, but he has to do this himself. We can't email teachers like we can for ds1's school, so if he doesn't sort problems himself during the school day he's stuffed.
