This is an individual exercise done at a table with out a mat. (Note: work cycle to be observed)
The child checks the exercises through the sense of sight, each pair of tablets having a different appearance.
Keep the steel tablet in the fridge at least half and hour before the presentation so that it is easier to differentiate it between the slate tablets.
The child lay out the tablets, put on a blindfold and pairs the tablets by temperature.
