Recently, we have been learning addition and subtraction within 10. Through reading the picture book "The Dreams of Gugu and Dandan," students discovered different ways to decompose numbers and helped Dandan find all the different ways to divide 10 sheep without missing any, training their sequential thinking in the process. In learning addition and subtraction within 10, students engaged in exploratory activities and discovered various methods to solve addition problems, such as counting all, counting on, number bonds, and using number lines. They discussed the connections between different strategies to choose the most effective strategy that suited them for solving addition problems. Later, G1 students practiced addition through various games, such as board games, rolling dice game, and Bingo.
