Students can represent something in a group. For example, they might together form the shape of their country. They can then move to where they would like to be in their country and talk about why they want to go there. Students can similarly form maps of their town, maps of a jungle and maps of their school. Mime is also useful.
Students act out a word and the others have to guess what it is.
You could have various items of clothing available such as hats, gloves, etc. to make roundelays, acting out, mime, etc. Physical activity doesn't have to be related to language learning. You might start a lesson or break up a long lesson by getting the students to do something, for example, shake their arms, stand up and turn round a few times or walk around the room.
