The Pink Tower Cards are a complementary material to the Pink Tower, designed to enhance visual discrimination and pattern recognition. Each card represents a different size of the cubes from the Pink Tower, allowing children to match them with the corresponding cubes. This activity promotes fine motor skills, spatial awareness, and cognitive development, encouraging children to deepen their understanding of size sequencing and geometry. These cards are a valuable tool for reinforcing concepts introduced with the Pink Tower in Montessori environments.
