An essential tool of the Montessori learning method, the Brown Stair control cards help develop the intelligence of children aged 3 to 6. The tool consists of 10 laminated cards representing each prism of another essential material: the Brown Stair. Being complementary, both tools should be presented to the child at the same time.
The Brown Stair control cards have two uses. First, they allow the child to rebuild the gradation of the stair. Second, the child can enjoy matching each card with its corresponding stair prism. In this way, the child develops their visual discrimination of dimensions and thickness. The purpose of this tool is to develop the child's logical thinking. It is therefore an excellent way to introduce them to mathematics from an early age.
