Why not starting with some easy riddles? We would be practicing our listening skills (also because they need to be read always a few times) and sometimes introducing new vocabulary in a funny way.
Internet is plenty of them, but I found this website´s riddles fun and easy for the younger students. We could also ask the students that win to come out to read the next riddle or simply take turns so in a few days all the class would´ve read one to the rest.
Have a nice day!
