In terms of providing supplemental information and caution, certain icons or boxes can be used in educational materials to signify additional context or to alert students to potential misconceptions, helping to guide their learning process.
For example, in a Venn Diagram, the area in the rectangle but outside both the circle and the oval can be described clearly, ensuring that the student comprehends the relationship between different sets.
