GPS in Montessori mathematics refers to the teaching method of sequence, pairing and classification.

Teaching activities and the use of GPS (sequence, pairing and classification) teaching methods, natural and orderly abstract symbols, through repeated operations of teaching AIDS, enable children to acquire the concepts of numbers and quantities, and then enter the four operations to cultivate their awareness of logical thinking. Montessori mathematics education begins with the understanding of continuous quantities (with the help of several sticks, children can intuitively compare the sizes of quantities and perceive that each quantity represents a set), and then understand the separated quantities. The content of Montessori mathematics education has been expanded, involving the concept of 0 and the practice of carry system. Fully understand the relationship between numbers of 1- 10 or 0- 10 with the help of sand boards, spindles, boxes and zero games, and with the help of boards, 100 boards, 1000 beads.

The content of Montessori education. Sensory education Montessori's sensory education includes the training of senses such as vision, touch, hearing, smell and taste. Visual training helps children to improve their visual perception of measurement and distinguish size, height, thickness, length, shape, color and different geometric shapes. For example, socket cylinder, cultivate the visual ability to distinguish thickness, height and size. Color swatch to know the color and distinguish the difference between light and dark. Geometric panel, geometric entity group, etc. Know all kinds of geometric shapes. Tactile practice is to help children distinguish whether an object is smooth or rough, whether the temperature is hot or cold, and whether the object is heavy, large or thin. For example: tactile board, temperature sensitive board, weight board. Hearing training is to make children accustomed to distinguish the differences of sounds, so that they can not only distinguish timbre and pitch, but also cultivate their initial aesthetic and appreciation ability. For example: sound tube, sound sensitive clock, etc. The training of smell and taste focuses on improving children.
