The Pertra “Concentration” box
The Pertra “Concentration” box deals mostly with spatial/positional differentiation. The visual figure/ground differentiation is the basis for guiding your concentration and attention. This fundamental ability is required to enable further development of the functions that are based on it. In serial activity, the child is required to observe the given sequences in their activity. Recognising seriality is a requirement for logical action.
