最近聆听了一位老师的《三位数乘一位数》。老师从学生的实际出发,引导学生把两位数乘一位数的笔算方法自主迁移到三位数乘一位数的笔算中,通过提供4个乘法来完成了迁移内化过程。
Recently listened to a teacher’s “triple digit by one digit.” Based on the students’ actual conditions, the teacher guided the students to migrate themselves digitally and digitally to three-digit and one-digit numbers. The process of internalization of migration was completed by providing four multiplications.
