Features: This book aims to help children firmly grasp the operation methods of addition through systematic practice from basic addition to calculation. Through repeated practice, it helps children lay a solid foundation for arithmetic skills in the first grade of primary school. The main objectives and structure of the book:
1. Firmly master the composition of numbers within 10 as the foundation of addition. The composition of numbers within 10 is an important foundation for learning addition and subtraction. This book helps children use both decomposition and composition methods for addition through repeated exercises such as "5 equals 3 plus 2" and "3 plus 2 equals 5."
2. Repeatedly practice addition within 10. At the beginning, through exercises like "how many after adding" and "what is the sum," children understand the meaning of addition. Then, symbols (, =) are used for repeated practice of addition. The exercises are structured into the first half focusing on addition within 5 and the second half focusing on addition within 10.
