How Differentiated Grouping Works

Differentiated instruction groups students by performance level so teachers can tailor instruction to each tier's needs.

Formula

Tier Count = Total Students x Tier Percentage

Groups = ceil(Tier Count / Max Group Size)

Three-Tier Model

  • Advanced: Ready for enrichment and extension
  • Proficient: On grade level, standard instruction
  • Struggling: Needs intervention and scaffolding

    • Smaller groups for struggling students allow more individual attention.

    Exemple Résolu

    28 students: 25% advanced, 50% proficient, max group size 6.

    1. Advanced: ceil(28 x 0.25) = 7 students, groups: ceil(7/6) = 2
    2. Proficient: ceil(28 x 0.50) = 14 students, groups: ceil(14/6) = 3
    3. Struggling: 28 - 7 - 14 = 7 students, groups: ceil(7/6) = 2
    4. Total groups: 2 + 3 + 2 = 7
