The following developmental skills and benefits are encouraged by Roller Rattle Musical Shape Instrument learning toy:

Roller Rattle Musical Shape Instrument develops Motor skills
Motor skills are actions that involve the movement of muscles in the body. They are divided into two groups: gross motor skills, which include the larger movements of arms, legs, feet, or the entire body (crawling, running, and jumping); and fine motor skills, which are smaller actions, such as grasping an object between the thumb and a finger or using the lips and tongue to taste objects or for speech.

Roller Rattle Musical Shape Instrument develops Fine motor skills
Fine motor skills involve a refined use of the small muscles controlling the hand, fingers, thumb, wrists, feet, toes, lips, and tongue.

The development of these skills allows one to be able to complete tasks such as writing, drawing, buttoning and speech. Fine motor abilities develop over time, starting with primitive gestures such as grabbing at objects, that develop into basic grasping and manipulation skills to more precise activities that involve precise hand-eye coordination in preschool years and onwards.

The preschooler becomes quite adept in self-help, construction, holding grips, and bimanual control tasks requiring the use of both hands. When the child enters middle childhood they make great progress in their artistic abilities. They begin to express themselves through drawing, sculpting, and clay modeling.

Roller Rattle Musical Shape Instrument develops Hand Eye Coordination
Hand-eye coordination is the ability of the vision system to coordinate the information received through the eyes to control, guide, and direct the hands in the accomplishment of a given task, such as handwriting or catching a ball

Roller Rattle Musical Shape Instrument develops Sensory stimulation - touch
Infants and young children first learn about the external and internal world through their senses of sight, sound, touch, taste and smell as sensory information is transmitted to the brain.

Sensory Integration involves the ability to take in the information gathered through the senses from the internal and external world and put it together in a meaningful way. The complex interplay between the various senses is necessary as the child learns about, acts and responds to the environment in appropriate ways. For example, a baby's sense of sight will help him or her reach out for a rattle on the table. The sense of touch will enable him to feel for and grab the rattle and to determine how much pressure to exert to hold and shake the rattle. The sense of hearing will allow the baby to distinguish the sound made by the shaking rattle. As all of this sensory information is processed, the child learns how to interpret and respond to various environmental cues.
