Nuts and Bolts Tripod Grasp
Purpose
This activity is a fantastic way to build fine motor strength and coordination without needing expensive toys. By matching and assembling the hardware, your child practices bilateral coordination (using both hands together cooperatively) and refines the precise finger movements needed for daily tasks like writing, buttoning clothes, and opening containers. It also engages visual perception skills as they scan the pile to find the matching sizes.
Activity Steps
Activity Steps
-
Preparation: Place a variety of nuts and bolts on a table or tray. If your child is new to this skill, start with just 2 or 3 large pairs to keep it successful and frustration-free.
-
Sort and Match: Ask your child to dig through the pile to find a “match” (one nut and one bolt that fit together). This helps them practice visual discrimination to tell the difference between sizes.
-
The Assembly: Have your child hold the bolt steady in one hand (their “helper hand”). With their dominant hand, encourage them to pick up the nut using their thumb, index, and middle finger. This is the tripod grasp.
-
Twist and Turn: Ask them to screw the nut onto the bolt. Watch to see if they can use their fingers to rotate the nut rather than moving their whole arm or shoulder.
-
Unscrew: Once they are all assembled, taking them apart is just as valuable! It uses different muscle groups and extends the play.
