This is a Montessori material called the "Horizontal Dowel with Discs." It consists of a wooden base, a vertical post, and a horizontal dowel with green circular discs that can slide along the dowel.

Features and Uses:

1. Fine Motor Development: Sliding the discs along the dowel enhances children's hand-eye coordination and fine motor skills.

2. Problem-Solving Skills: Encourages children to explore how to manipulate objects and understand spatial relationships.

3. Focus and Concentration: The repetitive action of moving the discs helps children develop their ability to focus and sustain attention.

4. Object Manipulation: Offers hands-on experience for children to practice grasping and moving objects with precision.

This material is designed for infants and toddlers (6-18 months) as an introduction to early motor and sensory skills. It supports independent learning and exploration, aligning with Montessori principles of self-directed activity.
