Stand in the centre, and show the two teams the same picture for five seconds. Team A has to phrase a correct question using 'is there any', 'are there some' etc. Team B has to give the correct answer. If the question is wrong, team B get a bonus point for correcting it, if the answer is wrong, team A get a bonus point for providing the correct answer. Answers should be in the correct form, ie yes there are some, is some, is a lot, are a lot, are a few, isn't much are 5, are two packs etc. Show a different set of cards each time and obviously change the questioning team each time. You should be careful to nominate a team spokesperson to ask and answer or the resultant chaos may be more than you can handle, this turns into a really active competetive activity with some really beneficial language interaction. Keep score on the board, teacher can add or subtract own bonus/penalty points for keen/disrutive team members
