The trick? They need to use a short stylus and play apps that require primarily drag-and-drop play. Stop them from only tapping that screen today, because tapping alone will not make much of a difference in strength and grading of force.
Why will drag-and-drop play work? The resistance of the stylus tip on the screen builds strength and control at the same time. They gain control as they get the immediate feedback from game play. Too much force? They get stuck and can’t move the styluses the target. Too little force? Again, the target doesn’t move. Could they revert to a fisted grasp and accomplish this? Sure, but that is exhausting, and you are within view of them anyway….right?
For this to work, young children need supervision, but not helicopter supervision. And they need to know that how they hold any utensil matters to you. My best approach to build grasp awareness is to appeal to their desire to be older. Tell your child that you have been watching them, and you believe they are ready to hold a stylus like an older kid. Oh, and you can explain to them how to hold the stylus the easy way. They just have to watch your example and play some games for practice. Yup, you ASK them to play on a tablet!
Best drag-and-drop games for young children? I like the apps from Duck Duck Moose, especially the Trucks and Park Math. Every app has some tapping, but you can select and “sell” the games that require drag-and-drop. There are apps that little girls can play to dress up princesses, mermaids, etc. Pick the ones where they have to drag the items over to the characters. Same with wheels on trucks, shapes into a box, etc. The Tiny Hands series of educational apps have a lot of drag-and-drop play.
Finally, mazes are wonderful, and so are dot-to-dots that require drag-and-drop play.
Have a really young child, or a child who struggles to keep their fingers in a mature grasp pattern without any force? Then apps that require just a tap are fine. I set the angle of my tablet at various heights (my case allows this) to prompt more wrist extension (where the back of the hand is angled a bit toward the shoulder, not down to the floor). When a child’s wrist is slightly extended, the mechanics of the hand encourage a fingertip grasp without an adult prompting them.
Try drag-and drop play with a stylus on your tablet today, and see if your child’s grasp strength starts improving right away!
