The Mini Cylinder Blocks (A021) are reduced-scale replicas of the four cylinder block sets used in the 3–6 sensorial curriculum to refine visual discrimination of dimension. Their smaller size makes them well-suited for teacher training demonstrations, shelf extensions for older Children's House children who benefit from increased challenge, or use in spaces where the full blocks are impractical. Having a mini set on hand also allows you to model the material clearly during parent education evenings without removing the classroom set from its designated shelf space.
