Our Abacus Level 2 Book is meticulously designed to advance young learners' arithmetic skills by introducing them to foundational addition and subtraction techniques, progressing to more complex formulas for enhanced calculation efficiency.
Initially, the book focuses on direct addition and subtraction methods, enabling students to grasp basic operations. This approach ensures a solid understanding of fundamental arithmetic principles.
Building upon this foundation, the curriculum introduces the Small Friends Formula, a concept that enhances mental calculation abilities. In this method, numbers are paired to sum up to 5, facilitating quick addition and subtraction. This technique streamlines calculations by simplifying number relationships.
The book further progresses to the Big Friends Formula, which involves pairs of numbers that add up to 10. Understanding this concept is crucial for efficient mental arithmetic, as it allows for rapid computation by recognizing these number pairs.
By systematically advancing from basic operations to these specialized formulas, the Abacus Level 2 Book equips students with the tools needed for swift and accurate mental calculations, laying the groundwork for more advanced mathematical concepts in future levels.
