Example exercises for the Pertra "Discrimination" box
The child learns the basics of classification in a cycle of exercises. Depending on the task, the child must highlight inclusive criteria and suppress the two other characteristics as ‘disruptive stimuli’. The suppression of these stimuli is a key requirement for attention performance.
Exercise 1: "Threading according to criteria"
Exercise 2: "Allocation into groups"
- Threading according to specified colour: size and shape are disregarded
- Threading according to specified shape: size and colour are disregarded
- Threading according to specified size: colour and shape are disregarded
A variety of beads are placed on the base board and the child is tasked with distributing them into 3 groups. They must first find the discriminating characteristic (colour) and distribute the beads accordingly.
Exercise 3: "Fill in the blanks"
Beads are threaded onto 4 rods on the base board. The pattern varies in some way from rod to rod. One bead is missing on rods 3 and 4. The child must identify the missing bead and allocate it accordingly.
Exercise 4: "Sorting"
The child must transport the discs, which are stacked according to size, onto another rod. In the process, the discs must be moved one at a time and a larger disc must never be placed on top of a smaller one. This exercise improves hand-eye coordination and skill.
