There's a good outdoor game on
http://www.montanalingua.com/fileadm...ndmansBuff.pdf .
Take your students outside for a more adventurous lesson. Language content of this lesson includes nouns such as "branch, slope", adjectives such as "steep, slippery" and instructions such as "keep going, duck".
Despite the name it's not at all like the original blindman's buff - no trying to guess who's who by feeling their faces - rather two students take responsibility for a third blindfolded student and lead him/her through a mild obstacle course.
Also available in German and French on
