TEACHER NOTES:
Students at the second-grade level should have experiences with simple fractions as they relate to everyday life experiences and expressed in the language the students bring to the classroom. The focus at this level should be on students recognizing when things are divided into equal parts rather than on fractional notation. Second graders should be able to identify three parts out of four parts, or three-fourth of a folded sheet of paper that has been shaded, and to understand that fourths mean four equal parts of a whole.[1]
