Mini Knobbed Cylinders (Set of 4 _ Each block 6.2" x 1.6")
4 mini knobbed cylinder blocks (Each block 6.2" x 1.6" (157mmx40mm)) with 5 cylinders in each.  The cylinders refine and apply the child's ability to discriminate dimension and prepare for mathematics activities involving comparison, grading and seriation. The child initially completes a single set of cylinders, later the sets are combined and the interrelationships in size are experienced. . Early Learning Goal: Use language such as 'greater', 'smaller', 'heavier', or 'lighter' to compare quantities.  Use language such as 'circle' or 'bigger' to describe the shape and size of solids and flat shapes.
