摘　　要：数学核心素养提出,要注重学生学习过程中的情感、态度、价值观以及感受解决问题策略的提出过程。本文以七年级下《图形面积与代数恒等式》这一节数学拓展课为例,以问题引导为主线,设计了一个“三环节”验证的数学拓展课,让学生在无意识中完成观察、猜想、验证的认识过程,感知几何图形的面积关系与代数恒等式之间的关系。并从《图形面积与代数恒等式》这一节拓展课的教学设计中,浅谈对于核心素养下数学拓展性内容教学的几点思考。The core literacy of mathematics proposes that we should pay attention to the process of putting forward the emotions,attitudes,values and feelings of problem-solving strategies in students’learning process.Taking the mathematical expansion course“graphic area and Algebra identity”in Grade 7 as an example,and taking problem guidance as the main line,this paper designs a mathematical expansion course of“three links”verification.Let students unconsciously complete the cognitive process of observation,conjecture and verification,and perceive the relationship between the area relationship of geometric figures and algebraic identities.And from the teaching design of the extended course of“graphic area and algebraic identities”,some thoughts on the teaching of mathematics expansive content under the core quality.
