Count and Thread Stones are a versatile math manipulative designed for sorting, sequencing, and fine motor development. This set includes 15 durable stones modeled after large buttons, organized into three color families. Each group of five features a varying number of holes, ranging from 1 to 5, allowing children to string and sort the pieces by color, shape, or numerical value. Their natural look and tactile finish make them an excellent addition to sensory bins, discovery areas, or math centers.
