Ordinal Number Hotel

Draw a 5 x 5 grid on the board. Each square represents a room of a hotel, you can draw some decoration if you wish. Number each sqaure as follows:
501 502 503 504 505
401 402 403 404 405
301 302 ...
201 ...
101 ... etc.

Each number represents the floor and room number of the hotel. For example, 305 means "third floor, fifth room". Put the students into teams. Have one person from each team come to the front. call a room, eg. "second floor, fourth room!". The students must run to the board and touch the correct room (204) with their hand. First to touch the correct room wins a pont for their team. Great for ordinal numbers.
