Learning to grasp is not only important in the development of hands as tools for complete daily living tasks, utilzing travel canes, utilizing tools for literacy, and many other things. Grasping also helps the learner be able to compare the density, texture and temperature of various objects. Even children with motor challenges can develop better skills in this area. 

Developmental Process in Learning to Grasp

Learning to reach and grasp takes time to develop. (You may want to Download "Promoting Comprehending Hands Through Active Learning" by Patty Obrzut, M.S., O.T.R/L). Learn more about various activities that support your child in learning to grasp.


Children are typically born with a grasp reflex, but it takes time for the development of a functional grasp that allows the child to explore and manipulate various objects. A voluntary grasp and release develops out of activities of scratching, banging, patting, and so forth. You may want to review Scratching, Batting, Banging ideas on Active Learning Space to learn more. There are several pieces of "perceptualzing aids" or equipment that provide great opportunities for a child to learn grasp. These include various Position Boards and the Little Room

Reaching is another skills that ties in with grasping. Children need to have activities included in their day that encourage reaching. You may want to review Reaching and Spatial Orientation on the Active Learning Space website to learn more about these activities.


Entangling Fingers

Chains BeadsWhen a child begins to be able to reach and scratch various surfaces, introducing items that allow the child's fingers to become entangled help the child practice grasping. You might begin with loops of yarn, bundles of elastic hair ties or scrunchies, ribbons and bows, crocheted or macrama fabrics, slinkys, chains, and other objects that allow a child to entangle his or her fingers easily.

Practice Grasping Using a Position Board

Position boards should be designed at various levels: Level 1 Scratching, Level 2 Grasp and Release, and Level 3 Grasp and Manipulate. If you child is not yet grasping, but using fingers to voluntarily attempt to grasp add items that are fixed onto the board. For example soap dishes made from rubber and metal, dish scrubbers, package bows, paper folded into a fan shape, and so forth. Keep the profiles low at first and gradually move to higher profiles like kitchen utensils, tools, toy cars, empty Altoid or other mint containers. When the child is demonstrating grasp while the object is in a fixed position begin to transition to objects placed on short elastic pieces. This allows the child to grasp and release an object, then be able to find it again. Though almost anything can be included in this type of Position Board, it is important to consider the size of the child's hand. Once the child is able to easily grasp and release, then transition to a Grasp and Manipulate level by extending the length of the elastic holding the object to the board. You will need to thread the elastic tubing to reduce the chance of the child cutting of blood flow to finger should they get them wrapped tightly in the longer cords. This also helps keep the objects from tangling up with each other. Below are examples of Position Boards at these different levels.

Practicing Grasping Skills in a Little Room

Description: This child in a Little Room accidentally, or purposefully, grasps and keeps, or grasps and releases objects. On several occasions, he also grasps and brings an object to his mouth. All of these movements are increasingly higher developmental skills. This child’s pushing and batting motions, with increased opening of the hand, allow grasping to occur. Note that this Little Room is well equipped with materials that respond appropriately to pushing and batting.

Exploring Kinetic Sand on a Mirror Tray

Description: This boy with cerebral palsy uses a raking motion to explore the objects in the kinetic sand in front of him. As an adult moves the objects, notice the slight changes in the way he uses his hands and fingers. The kinetic sand on the mirror tray allows the objects to stay in place, so that he can more easily find the objects.

 Rain Stick and Steel Drum

Description: In this video we see that the boy demonstrates difficulty rotating his wrist in order to activate the rain stick. In the second part of the video, notice how he compares the sound of dropping the beads in the steel drum versus the ping pong balls, and eventually puts the beads down to engage both hands in dropping ping pong balls in the steel drum.

Grasping while Drumming

Description: This boy transitions from banging on noise-making surfaces with an open hand, to using a tool to bang on various drums. You will observe that whether or not he uses his hand or the end of a drum stick to contact the surfaces, often depends on the length of the stick, and where the stick is positioned in his hand, as he is still refining this skill.

Pincer Grasp

Using a Massaging Brush to Develop Pincer Grasp

Description: In order for a child to isolate the finger movement necessary to develop a pincer grasp, the child must be given objects with grooves and contours to explore. Watch in this video as a child isolates a finger to find the hole at the center of a massaging brush. Using only the hand and fingers, the child also learns how to stop the brush or slow it down.

Provide a variety of materials for your child to explore by poking his fingers inside. These can include both large and small items. Below are some examples of objects and materials that your child might explore by poking his or her fingers in the holes.

Taking Things Apart and Putting Things Together

Description: A young boy takes things apart, puts things together and bangs objects with two hands. If given the correct environment, he will start to use his hands for more and more constructive activity.

Steps in the Developmental Process of Grasping 

In her book The Comprehending Hand, Dr. Lilli Nielsen lists the various steps in the developmental process involved in the ability to grasp:

  • hand to mouth
  • hand to hand
  • objects held in hand
  • objects held in hand put to mouth
