Analysis involves not only seeing the parts but a sense of what is and is not part of the whole or entity being studied. Analysis is carried out when the child separates out from the pile the border pieces, common color sections and noteworthy patterns shared by other pieces. It is not necessary to have all of the pieces to make a sound determination of what pieces belong to what puzzle. Mixing pieces of another puzzle with the one being completed provides a concrete exercise in understanding this missing pattern sense of analysis. Comparison involves finding similarities and differences between different pieces of the same puzzle or pieces from different puzzles.
Evaluation puts the puzzle on a scale and compartively weighs their worth using some criteria.
These criteria are often referred to as values. The child might be asked what features of puzzles they like and then follow by asking whether that features was present or not present in the given puzzle. This consideration can be extended upwards.
