Montessori Mathematics is a book specially designed and arranged for children's kindergarten mathematics learning, which is classified according to children's psychological and physiological age characteristics. Next, Bian Xiao will bring you the educational content of Montessori mathematics small class. First of all, education is divided into two volumes. Children in small classes also learn mathematics in stages. Accordingly, the teaching materials of the small class of Montessori Mathematics are also divided into two volumes, namely, the first volume of Montessori Mathematics 1 and the second volume of Montessori Mathematics 2. This classification makes education more detailed. Second, the content of Montessori Mathematics 1. Learning content: color matching, seeking common ground while reserving differences, classification, sorting by law, correspondence, understanding length, sorting by length, distinguishing "1" from multiple, ratio, points within 3, points within 4, points within 5, circle, square, figure classification, and up-and-down distinction. The content of Montessori mathematics II. Learning content: pairing, classifying by one feature, becoming the same, sorting by size, comparing heights, sorting by height, correspondence, formation of 2, formation of 3, formation of 4, formation of 5, combination of objects within 5, visual grouping, cognition of rectangle, cognition of triangle and cognition of inside and outside. From the above analysis, it can be seen that Montessori Mathematics has carefully classified the mathematics learning content of small classes, which makes children's mathematics learning foundation more solid. Therefore, children in this learning period choose "Montessori Mathematics" to study mathematics.
