Note down your ideas before comparing them with my own comment. A learner tells the class a story in L1. Another learner interprets it into English for the rest of the class. They can ask questions about it in English. Groups within the class act out a difficult situation first in L1 and then in English.
Learners carry out a traditional written translation exercise.
They translate to or from English and compare results with each other. Learners form pairs to carry out what is known as 'back translation'. One learner translates a few lines from English into L1. Their partner translates them back into English without seeing the original. They compare results.
