The Montessori Knobbed Cylinders are a quintessential Montessori tool for refining a child’s visual discrimination of size and dimension. These four blocks, each containing 10 cylinders with knobs, help children understand differences in height, width, and diameter through hands-on play.

🔷 Set 1: Both the height and diameter of the cylinders decrease, helping the child recognize overall size differences.  

🔶 Set 2:The diameter decreases while the height increases, introducing comparisons of width and height.  

🔷 Set 3:The diameter decreases while the height remains constant, focusing the child’s attention on width.  

🔶 Set 4: The height decreases while the diameter remains constant, further developing the child's perception of size.

Each cylinder fits perfectly into its corresponding well, providing immediate feedback and giving the child a great sense of accomplishment. The blocks feature a control of error, ensuring that even young children can use them successfully, encouraging independent learning and self-correction.

🔷 As children become more confident, they can work with multiple blocks at once, experiencing the interrelationships between sizes and shapes.  

🔶 Use descriptive language like "taller," "smaller," "heavier," or "lighter" to help children compare and describe the size and shape of the cylinders, supporting the development of everyday mathematical vocabulary.

This material prepares children for math activities such as comparison, grading, and seriation, while also fostering problem-solving skills as they recognize and describe patterns in size and shape. Suitable for home or classroom use, the Montessori Knobbed Cylinders are perfect for children exploring early geometry and measurement concepts.

🔶 Dimensions: Approx. 45 cm x 7 cm x 6.5 cm (excluding knobs).  

This versatile educational tool offers an enriching, multi-sensory experience that lays the foundation for essential early learning skills in mathematics and spatial reasoning.
