This set of blocks is an excellent educational toy for introducing the ideas of height and depth using three natural wood nesting blocks and three coloured cylinders. The nesting blocks measure 5.5 cm (about 2") square and 10.5 cm (about 4") tall, and have nests of different depths on one end and identical depths on the other. The cylinders are 3.5 cm (about 1.5") in diameter and range from 3.5 cm to  7 cm (about 1.5" to 3") in height.  Combine the cylinders and the blocks in different ways either individually or as a stack to see how they all fit and relate to one another. All six pieces are made of eco-friendly rubberwood, and the colours are water-based stains that will not chip of flake.
