Do you mean you are carrying on covering this theme with the present cohort, or that you do it every year and are getting ready to start it with the present cohort? Is it covered as a topic or because there is a clear need among the children? Perhaps, if you feel bored, it is time for a change? You might feel, for instance, that the exploration of feelings can be best addressed when there is a specific issue in the classroom, when it arises naturally from events. Exploring feelings can be done through role play, with puppets, circle time, stories and story telling, and exploring body language and facial expression. Most children at this age see things as either "happy" or "sad", so to extend their awareness if makes sense to explore other emotions that they might feel such as "angry", "lonely", "excited".
