First up of our Montessori series - knobbed Cylinders set. There are four different blocks of knobbed cylinders. Block 1 varies in height and diameter, and the tallest is also the widest. Block 2 varies in diameter. Block 3 varies in height and diameter, and the tallest has the smallest diameter. Block 4 varies in height. Knobbed cylinders help develop the child's visual discrimination of size, which prepares the child for later work in math. Handling these knobbed cylinders also indirectly prepares and strengthens a child's hand for writing.
Retails at $15 per set for 4 sets of 15×4×6cm cylinders.
