Features: This book aims to help children firmly grasp the operation methods of addition through systematic practice from basic addition to calculations. Through repeated exercises, it helps children build the foundational arithmetic skills needed for first-grade learning. The main objectives and structure of the book:
1. Solidly master the number composition within 10 as the foundation of addition. The number composition within 10 is an important foundation for learning addition and subtraction. This book helps children master the methods of decomposition and composition for addition through repeated exercises such as "10 equals 3 plus 7," "3 plus 7 equals 10," and "how many more make 8."
2. Repeatedly practice subtraction within 10. At the beginning, through exercises like "how many are left" and "how many are missing," children understand the meaning of subtraction. Then, using symbols (+, =), they practice subtraction repeatedly. The exercises include subtraction with 0 within 5, subtraction within 10, and subtraction with 3 numbers.
