Fill it with rainbow rice on Monday morning. By Tuesday, children have sorted by color, built a story, and asked to refill it themselves. The flagship of our sensory tray range, designed by Button & Bug's certified pediatric occupational therapist and cut to order in the USA by a small woodworking workshop, from furniture-grade hard maple. Seven graduated color wells run along the surface, and the food-safe finish wipes clean and stays smooth through years of daily classroom use. Developmental benefits: Open-ended sensory exploration with any fill material Color recognition, sorting, and early mathematical patterning Fine motor control through scooping, pouring, and precise placement Narrative and dramatic play scaffolding through themed tray shapes Extend the play: Fill with rainbow rice, dyed pasta, or sorted loose parts and let children sort, pour, and pattern by color. Fill is not included.
