Kidy Learn Concentration ruler with sensory elements. The Kidy Learn Concentration collection consists of school materials equipped with sensory elements that improve concentration. The Kidy Learn Concentration ruler is made of highly transparent PET material. Two-coloured, convex scale and clear font increase legibility. Highlighted dots every 5 cm. The ruler's rubberised grip zone increases stability when drawing. Four sensory elements along the entire ruler stimulate the sense of touch, which is especially important for aesthetes (people who learn most easily through action, movement and experience). Touching and pressing a surface with a different texture to a smooth ruler helps them to concentrate. Ruler length 20 cm. Sensory and anti-stress toys help you to relax and relieve tension. They allow pupils to concentrate more on their tasks and avoid distractions. Children feel calmer and more confident. Repetitive movements such as kneading, rubbing, squeezing and twisting can stimulate the brain, encourage creative thinking and improve memory. The movement of the fingers and hands helps the baby's brain to maintain concentration.
