hey

I've just found this web and immediatelly decided to sign up
I'm training to be a teacher.. and for next Tuesday I need to prepare a lesson for children at the age of 13 about there is/there are and some/any (I've got only 45 mintes to present all these, and then to practise ) Oh, most of the children have just started to learn English... any ideas of funny ways to present these grammar pointsand then practise them??
