It’s simple for the kids to pick up "Do you have a ...?" when talking about one specific thing.

Split the group into several groups.

Assign each group a different word (this is the thing that that group wants to collect.)

Give each child mini-picture cards.

The students then go round asking as many people as possible "Do you have ......." (for example the "turtle" team asks "Do you have a turtle?")

If the student still has the object he/she says "Yes, here you are!" and gives it to the person who asked.

If they have already given it away, then they say "No, I'm sorry" and walk off.

The group that is the first to collect as many of their items as there are students in the group (e.g. 10 items for a class of 10 kids), sits down and they are the winner!
