Have your students write the words Zimmer-Nr. in one column and Euros in another. You then have them pretend that the hotel manager is asking his secretary to get the invoices ready for the guests who are leaving. Read out the room numbers and the sums of money. Have them write down the room numbers and the respective amounts of euros in figures and words. For example:
Make a column and list from a-d; for example
a. (Zimmer no. achtzen) 18 - 58,80 - acht und fünfzig
b.(Zimmer no. zwanzig) 20 - 75,00 - fünf und siebzig
c.(Zimmer no. ein un dreissig) 31 - 136, 58 - hundert, sechs und dreissig, acht und fünfzig
d.(Zimmer no. vierzig) 40 - 205,98 - zwei hundert fünf, acht und neunzig
This is a very good game for practice with numbers, since numbers are very difficult to get the hang of, and dealing with money is important in any language.
