Introduce children to the power of reflection and geometry with our sleek Mirrored Magnetic Polydron. This set encourages your child to think creatively while also building hand-eye coordination and motor skills through sorting, stacking, shape recognition and logical thinking. Children are able to use STEM principles to creatively build 2D and 3D structures using spatial thinking, polarity, problem solving, balance, and structure design. Beginners can begin with simple shapes like cubes or pyramids and advance to larger more complex structures. The reflective mirror properties of each piece add a whole new dimension to classroom learning. It is fully compatible with all existing magnetic Polydron sets. The Mirrored Magnetic Polydron is manufactured with high-quality ABS and is BPA free. This 48 piece set contains 18 triangles, 18 squares and 12 pentagons. When playtime is over, use the magnetic power to stack the pieces for quick and easy storage. An idea booklet is also included for easy guided building. This durable 48 piece set is an ideal addition to early childhood classrooms, preschools, and the home environment. This product can be cleaned and sterilized with an alcohol based sanitizer. It is recommended for children ages 3 years and up.
