Usually kindergarten has already started to learn numbers. In addition, kindergartens need books such as schoolbags, pencils, exercise books, pencil boxes, erasers, etc.

A counting stick, a Montessori mathematics teaching aid, is composed of 10 red and blue wooden cuboid sticks. It is mainly used to learn the numerical names of 1 to 10, and the corresponding quantity of each number, and to remember the numerical order of 1 to 10.
