It can be a useful tool to help students stay focused, therapists agree.

More accurately, a distraction, argue teachers.

No, it's just fun, say kids.

The one thing everyone can agree on: fidget spinners -- the colorful, hand-held twirly device trending in area schools -- are here to stay, at least for a little while.

Fidget spinners, which come in a variety of styles, sizes and colors, are all the rage. Stores can't keep them in stock, and youngsters are collecting them by the handful.

But what exactly is a fidget spinner and why are kids finding them so appealing?

Third-graders in Massillon City's Whittier Elementary School said they like playing with the inexpensive spinners, which can be personalized. Kids are spending hours learning tricks and trading them with friends.

School officials see the value in a toy that can be used to keep students who have trouble sitting still and paying attention on task. But, say teachers, the spinners have become more of a disruption in the classroom than a helpful tool.

Keeping little hands busy

Similar spinning toys have been around for decades, but it wasn't until the last few years that fidget spinners have been more widely sought after, and the popularity of the toy has exploded locally in the last few months.

The 3-inch device can be found in gas stations, toy stores and online.

A basic fidget spinner is a two- or three-pronged sphere with a bearing in its center, circular pad. A person holds the center pad while the prongs spin. They can be made of various materials, including brass, stainless steel, titanium, copper and aluminum, and different types of bearings can produce varying spin times, vibration and noise.

Fidget spinners and other devices in the fidget category can be useful tools in helping children, especially those with Attention Deficit Hyperactivity Disorder, stay focused in school so they can learn.

Improved concentration was noted in some children who played with the device, which can provide an outlet for excessive movement, said Sarah Groves, a mental health therapist at Akron Children's Hospital.

The fidgets allow restless kids to release excess energy in an appropriate manner, she explained, which is helpful when restraint is called for, such as during a long car ride, in church or in the classroom.

"The purpose of a fidget is to exert some of the excess motor activity that kids sometimes struggle with," said Groves. "Fidgets help keep hands occupied and help the child to learn to self-regulate when feeling restless. It's similar to an adult doodling at a meeting. It allows them to stay more in tune with what they are suppose to be paying attention to."

A 2015 study published in the Journal of Abnormal Child Psychology, looked at 8- to 12-year-old kids with ADHD, and found those who participated in gross motor activity -- meaning the movement of limbs or large parts of the body -- performed better than those who sat still during tasks involving working memory, which is a type of memory used for processing incoming information. Exercise has also been proven to be helpful for kids with ADHD.

Tool or toy?

For some students, fidget spinners cross the line from tool to toy, and the twirling becomes a distraction in the classroom.

While area educators have not banned fidgets from schools, some teachers are not allowing kids to have them during class time, and others have asked kids to leave them at home.

Massillon Intermediate School Principal Jarred Zapolnik said he asked his students to stop bringing the devices to school because -- beyond being a hindrance in the classroom -- kids were selling them to other students for a profit.

"We don't want to see them or hear them in school," he said. "If they have one they have to turn it into me and their parents can come and get it."

Zapolnik said children with special needs have other, school-friendly options for fidgeting.

Wooble seats, which allow kids to move around in their seat, stress balls and even special erasers are all tools utilized in Zapolnik's school.

"A lot of kids have been using these types of products for years," he said.

At Whittier Elementary, Principal Matt Plybon is treating the device as a toy.

"We encourage our kids to leave their toys at home," he said. "Anytime a kid brings a toy -- whatever that might be -- to school everyone wants to play with it."

Plybon applauds the benefits of fidget spinners for idle hands during long car rides, but believes a better alternative for students during their free time at school would be reading a book.

For the most part, Whittier students have been leaving their spinners at home.

Brayden Keller has ADHD. He says his fidget spinner has helped him concentrate on tasks such as homework.

The 10-year-old Whittier third-grader says gets distracted easily and the fidget spinner helps him regain his focus.

And, he admits, they're a lot of fun to play with.

His classmates Mason Lantz, 10, and Brooklyn Jones, 8, also enjoy spinning the toy and doing tricks like balancing it on their noses and foreheads while it spins.

Lantz said he has five fidget spinners while Keller has seven and Jones has one.

Therapist Groves said there are number of products that fit under the fidget category, and many could prove more beneficial for a child.

Fidgets can be as simple as a piece of Velcro placed under a student's desk that he or she can touch and rub during class, to beads on a piece of string, or an exercise band.

Groves said parents may play the biggest role when it comes to figuring out it fidgets are fitting for a child. Most important, she advises, is setting rules and expectations for how, when and where a child should use the device.

Parents also should stress that fidgets should not be thrown, or used to taunt or hurt others.
