Crystal Connectors Building Discs | 300-Piece Colorful STEM Construction Set
Bring creativity, collaboration, and hands-on learning into your classroom with the Crystal Connectors Building Discs, a versatile construction set designed for children ages 3 and up. This engaging set includes 300 standard-size discs, each measuring between 1½" and 2½" in diameter, making them the perfect size for little hands to grasp, connect, and build. Each durable plastic disc is designed with eight slots, allowing students to construct imaginative 3D structures that extend in all directions.
The **brilliant colors—red, yellow, blue, and green—**make the building process even more exciting while offering opportunities for children to practice color recognition, sorting, and pattern-making. When used on a light table, the translucent discs provide a whole new level of discovery, allowing students to explore color mixing, reflection, and visual effects as they build.
More than just a fun activity, Crystal Connectors foster critical STEM learning skills. As children experiment with stacking and balance, they develop spatial reasoning, engineering design, and problem-solving skills. Working together in groups promotes cooperative play, communication, and teamwork, making this set an excellent choice for collaborative classroom activities.
Crafted from durable, easy-to-clean plastic, these discs can withstand daily use in busy preschools, classrooms, and early learning environments. Simply wipe with mild soap and a damp cloth for quick cleanup.
Encourage imagination, exploration, and skill-building in your classroom with the Crystal Connectors Building Discs, a must-have resource for early educators who want to combine play with purposeful STEM learning.
