You may want to see how much of that money that you personally will be able to decide how to use. The budget for the whole department is probably 5,000,000, and there are many things that will come out of that. Some good things are technology, mid-sized white boards, fake money sets, DVDs that have hard coded Korean subtitles, for sure lots of markers (I go through a lot in one year with the group white boards), dictionaries (Korean to English - quite expensive also)...Ah, I tip about the while boards - get the two sided ones, otherwise students will write all over the backs of them and you can't get it off.
