Lesson SEN 13
Task: Pick up objects with fingers.
Prerequisites: SEN 12
Concept: This activity is an extension of picking up objects with the hands (SEN 12). The fine-motor skill level is more intensive than when the whole hand is used to pick up an object. The lesson begins with the thumb and all fingers being used in a grasping manner and proceeds to the level of a thumb and forefinger grasp, also known as a pincer grasp.
Behavioral Objective: When requested to "please pick up" an item that is small enough to be picked up by a pincer grasp, the student will do so to a 90% accuracy level for 20 such items.
Materials: Spring-loaded clothespins, Cheerios (or similar items), and small objects common to the environment that are of a size where all fingers and the thumb would be needed to pick up and hold them.
Task Analysis:
1. Review with the student the concept of picking up items using his or her hand.
2. Modify Step 1 by gradually introducing objects that can be picked up just using all four fingers and the thumb.
3. Introduce to the student a spring-loaded clothespin and demonstrate the action needed to open and close the pin. Provide physical guidance to the student as needed and reduce that prompting until the student can independently open and close the clothespin. If muscular ability with this activity is weak, continue this task until the student is capable of performing the opening and closing for a number of times during a class setting. This activity mimics the pincer grasp.
4. Introduce Cheerios or a similar desired food and guide the student to pick these items up with a pincer grasp. Allow the student to eat the items picked up, especially if this is a desired food. Reduce all needed prompting and continue until the objective is met.
