A little bit of fidget, that's quiet, can't hurt...research supports movement and even doodling as being supportive of concentration. Don't be intimidated to try a new approach to support a child's learning through improved attention. Fidget toppers vary between nut/bolt, wing nut, square on a bolt, and nut on a ridged bolt. Each pencil is different and the fidget gears can be changed to a new pencil. D, RP, PC, PFE *
