A chart is a good means or aid of teaching. It brings environment to the process of teaching inside the class indirectly. Instead
of visiting the actual fields of a lesson in real life, the chart can
bring such scene into class to be seen by learners. The purpose is to
give life to the theoritical learning.It facilitates the process of
presentation in class.A common, effective teaching method is to use visual presentations in a
classroom. Charts and diagrams are especially helpful, as they enable
students to see ideas visually laid out in an organized way. Also,
visual tools can help the students process content and to make
connections more easily. Teachers can purchase or make charts to display
around the room, or create a chart as part of a lesson. These tools are
especially useful in elementary school, where children tend to have
shorter attention spans.
