This game is a fun way for students to practice sentence-structure.
To prepare: You need to write down sentences and cut them into smaller bits. Considering your age group, you may want to ommit capitalization, punctuation, etc. or mark them in another colour. You may also want to consider collocations (cut between them on purpose or keep them together). You also need to bring some tape.
The activity itself: Every students gets a part of a sentence sticked to their back. As soon as you allow them, they should check the phrases the other players have and try to line up so you are able to read the correct sentence. They are not allowed to tell the others what their phrase is. After they have figured out the solution you may want to ask them why a certain part of the sentence has to be in this position (especially helpful if students struggled with a specific sentence).
