Flip charts are large pads of paper used with an easel as a visual aid for presentations and group work. They can be used to display agendas, objectives, instructions for activities, and capture group ideas. Flip charts are versatile, require no technology, and encourage visual learning and participation. However, they are best for groups of 35 or fewer and require legible handwriting from the presenter. Key tips include using different colored markers, leaving space, and practicing to develop skills in effective flip chart use.
