Teachers have to start the lesson with a warmer to calm down kids and get them focussed on a lesson. It is the essential part of teaching. Since it is the first activity of the lesson, the warm up sets the tone for the next hour. It should be 3 to 5 minutes with an engaging, fun activity. It doesn’t require time consuming planning in advance. You can use songs, flash cards, mimics, puzzles, games like bingo etc.
