What is flexible grouping?

• A. Grouping students by age only.
• B. Grouping students according to shared instructional needs and abilities and regrouping as needs change. Group size and allocated instructional time may vary among groups.
• C. Keeping fixed groups throughout the year regardless of needs.
• D. Mixing all students in one homogeneous group.

Answer: (B)

Flexible grouping means arranging students into small, instructional groups based on their current readiness, strengths, and needs, and then reorganizing those groups as those needs change. The key idea is that groups are not fixed; they shift to fit what students are ready to learn next, and the time and group size can vary for different tasks.

This approach supports differentiation by allowing the teacher to target instruction to each group’s level, provide appropriate supports or challenges, and move students to more advanced groups as they progress. For example, in a math lesson, students might start in groups that work on foundational skills, and as a result of ongoing assessment, some move to a more advanced group while others receive targeted reteaching. In reading, groups can be formed around specific strategies or competencies and reshaped as students’ decoding or comprehension improves.

Grouping by age alone misses the actual learning needs, fixed groups don’t adapt when students grow or struggle, and mixing everyone into one homogeneous group eliminates opportunities to tailor instruction.
