8-Piece Discovery Windows | Fillable Wooden & Acrylic Sensory Blocks
Transform everyday block play into a hands-on learning adventure with the 8-Piece Discovery Windows Fillable Wooden Blocks Set. These innovative hardwood-framed blocks feature clear acrylic windows that allow children to explore objects, textures, and natural materials in an interactive and meaningful way.
Each block measures 4 inches square and 1.75 inches deep, making them the perfect size for little hands. The removable wooden ends make it easy for teachers and caregivers to fill the blocks with dry items such as leaves, seeds, sand, beads, fabric, or small classroom treasures (contents not included). Once filled, the transparent windows invite children to observe, compare, and discuss what they see.
Discovery Windows turn block play into a science-rich exploration experience. Children can go on nature hunts to gather materials to place inside, or participate in guessing and identification games that build observation and reasoning skills. As they examine the items inside, they naturally begin conversations about color, texture, size, shape, and properties of objects, strengthening both vocabulary and early science understanding.
Designed for children ages 2 and up, these blocks support sensory exploration, language development, and critical thinking. Durable hardwood construction ensures long-lasting classroom use, while the versatile design makes them a valuable addition to block centers, sensory tables, and discovery areas.
Whether used for nature studies, sorting games, or open-ended sensory play, Discovery Windows encourage curiosity, conversation, and creative learning through hands-on exploration.
