Informal learning arises from daily experiences and interests, rather than formal objectives. It involves acquiring attitudes, values, skills and knowledge without intentional learning. An exhibition displays selected items, usually temporarily, to impart information and teach through images in an informal way. Math fairs allow students to learn about math concepts through hands-on exhibits and activities. They can be teacher-driven with stations set up by educators, or student-driven where students create their own projects to present and be judged on. The fairs aim to popularize math, foster creativity, build relationships, and identify and motivate gifted and struggling students.
