Which of the following skills does not belong to graphomotor skills?

The skill that does not belong to graphomotor skills is understanding sentence structures. Graphomotor skills primarily involve the physical aspects of writing and drawing, which includes the mechanical processes of handwriting, visual perceptual processes of graphics, and the handwriting mechanics required for producing written language.

Understanding sentence structures, however, pertains more to the cognitive and linguistic domains of language learning rather than the physical act of creating written text. This involves comprehension of grammar, syntax, and how sentences are formed, which are essential for effective communication but do not involve the motor skills associated with writing. Therefore, recognizing that understanding sentence structures falls outside the realm of graphomotor skills helps clarify the distinction between these cognitive and physical processes involved in literacy development.
