三部分卡以图文配对与三阶段教学为核心，帮助孩子建立物象与词语的清晰连接，循序扩充词汇量，并提供自我检查（控制误差）。由绿荫教研团队精心策划、设计与制作——一支由蒙特梭利专业认证教育者组成、具备数十年课堂经验的团队——确保每份材料贴近幼儿的发展需求，适合教师和家长在课堂与家庭中使用。

The Three-Part Cards use picture–word matching and the 3-period lesson to build clear object–word connections, steadily expand vocabulary, and provide a natural control of error. Thoughtfully curated, designed, and handcrafted by Greentree’s academic team — accredited Montessori educators with decades of classroom experience — these materials are closely aligned with children’s developmental needs and suitable for educators in classrooms as well as for parents at home.
