Who recognizes these rings? 

These are the rings that need to be put in the correct order. This simple board is a sorter and an abacus introducing kids to the world of basic math. The toy supports development in many areas. It teaches color recognition, sorting and counting.

The board is not painted. The Bajo company makes sure that every toy has a wooden element without any coat of paint in order for children to get to know, see and feel the structure of wood.
