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