I like the idea of having the boy helpout with the younger children - I'm sure that would help both you and him and would probably give him a lot of skills for later on in life. I know at one of the Youth Clubs I used to go to here in the UK, they used to pick the older children to help out with re younger children if they were doing something like cooking etc.

I too have lots of ideas for girls seeing as I am one and of a similar age but I don't have that many ideas for boys unfortunately!! I have seen boys play at my school and they tend to like the games consoles etc so that might be something to look into if you haven't already got any!! Do you have any of re paper models that you could build? A lot f the younger boys round here like to build wooden paper airoplanes from kits that they have and they are quite practical also!! A lot of the boys that I know like making cards or something crafty with lots of different things so that might be something to look into also!

A lot of the teachers ad child minders here also like to run projects with the older kids so it might be an idea to do a project on drugs and alcohol, relationships, growing up etc. I have done one of those projects before and I really enjoyed it and the teachers made it fun as well as interesting so it didn't feel like school work!!

Hope this helps a little and if you need anything, feel free to PM me as I am a teen and might be able to help!!
