those arnt hard chores to do, but if you want them to clean try to let them do a more fun way of doing it like,if they get do there chores all week you give them a surprise, something small.or you give them a punishment if they dont do it. i have a duaghter that is 9 and a son that is 10. my son doesnt like cleaning so if he doesnt clean his room he gets grounded from his freinds something like that. hope i have been a help even know its a litt;e late sending it.
