# Summary Chapter 19 - 1912 - The Montessori Method ### **Short Summary** This text discusses the Montessori method of teaching numeration and the introduction to arithmetic. It emphasizes the use of concrete materials and real-life examples to teach children counting, addition, subtraction, and multiplication.  ### **Facts** * 💰 Counting with money, such as using coins, is an effective way to teach numeration to children. * 📏 The Montessori method utilizes sets of blocks, specifically the series of ten rods used for teaching length, to introduce numeration and counting. * 🔢 Children learn to count the sections of the rods, starting from one and going up to ten, and also name the rods from shortest to longest. * 🧮 Graphic signs, such as sandpaper numbers mounted on cards, are used to represent numbers and teach their association with quantities. * ➕ Children engage in exercises that involve associating numbers with quantities, using trays divided into compartments and objects to match the number indicated. * 🌀 The concept of zero is introduced through games and activities that help children understand that zero represents nothing. * 🧠 Memory exercises are employed to reinforce recognition and understanding of written numbers, where children draw slips of paper with numbers and select corresponding quantities of objects. * 🎲 Addition and subtraction are taught using the same rods used for numeration, with an emphasis on forming tens and understanding the concepts of addition and subtraction through concrete examples. * ✖️ The concept of multiplication is introduced when children discover that two rods of five make ten, and they explore various combinations to form different numbers. * ➖ Subtraction is reinforced through the reverse process of taking apart rods that formed tens, and children learn to subtract numbers up to ten. > ##### **The License of this page:** > > This page is part of the “**Montessori Restoration and Translation Project**”.\ > Please [support](https://ko-fi.com/montessori) our “**All-Inclusive Montessori Education for All 0-100+ Worldwide**” initiative.
