The teacher of a multigrade self-contained special education classroom considers the needs and abilities of the following students to group them for an upcoming mathematics lesson.
Student 1 is a first grader with the following IEP goal. "Given paper circles and squares, the student will fold the papers and identify one-half and one-fourth of the whole with at least 80% accuracy."
Student 2 is a second grader with the following IEP goal. "Given a variety of concrete fraction models of halves, fourths, and eighths, the student will correctly name the fractional parts with at least 80% accuracy."
Student 3 is a third grader with the following IEP goal. "Given a set of ten one-step problems involving addition and subtraction of fractions with like denominators, the student will solve them with at least 80% accuracy."
Student 4 is a fourth grader with the following IEP goal. "When shown the first two steps of a pattern, the student will extend the pattern twice with 80% accuracy on three consecutive days."
Based on the students' IEP goals, which of the following grouping formats is most appropriate?
A.Allowing the third and fourth graders to tutor the first and second graders
B.Working with each student individually on specific learning objectives
C.Teaching the first and second graders together while the others work independently
D.Keeping all four students in a whole-group differentiated lesson on fractions
