Montessori Small, Medium & Large Sorting Activity
Introduce children to the concepts of small, medium, and large with this hands-on Montessori sorting activity.
Designed to encourage independent exploration, this activity helps children develop visual discrimination, observation, comparison, and classification skills using three-dimensional miniature objects.
Children can examine, compare, and sort the objects into three size categories using the included sorting mat.
Two activity options are available. Please select your preferred set from the variation menu.
