Features: This book aims to help children firmly grasp the methods of addition through systematic practice from basic addition to calculations. Through repeated practice, it helps children lay a foundation for their 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, use symbols (+, =) to repeatedly practice addition. The exercises are structured with the first half focusing on addition within 5 and the second half focusing on addition within 10.
