'Elf' is of course the German word for 'eleven' and this game is used to practise numbers 1-11.

Simple version:

Students stand in a circle with a chair behind them. They take it in turns to say the numbers 1 to 11 in order. The person who says 11 is 'out' and has to sit down.

Far more fun version:

As above, but each student can choose whether to say one, two or three numbers. This leads to strategic choices to avoid getting out, particularly when there are only a few players left.

Cautions:

Students in larger classes can get bored/distracted/disruptive if they are waiting for their turn or are out and waiting for the round to finish. Be alert to students trying to get others out as a form of bullying.

Extensions:

This game can be adapted for any vocabulary set where there is a fixed sequence, e.g. months, days, colours in a rainbow.
