This series of prisms helps the child to visualize the increase in height and width while the length (20cm) remains constant. Working with a brown ladder indirectly prepares the child for the concepts of geometry, area and volume, develops his coordination and fine motor skills. The child learns to compare and insert and develops his vocabulary related to sizes (large-small, heavy-light, wide-narrow, etc.).
The brown ladder is a series of 10 wooden prisms whose heights and widths increase in exact progression from 1x1x20 cm (the smallest) to 10x10x20 cm (the largest).
This product is a teaching material, not a toy. Not recommended for children under 3 years of age without supervised by an adult.
