数学猜想实际上是一种数学想象,是人的思维在探索数学规律、本质时的一种策略。猜想在数学教学中具有重要作用,结合小学苏教版教材(二年级下册)86页第六单元的这道“和是1089”的数学复习题的教学设计,就数学猜想策略的教学实践,以及具体如何引导学生进行合理的猜想,进行相关的探索、验证、质疑、反思。
Mathematical conjecture is actually a kind of mathematical imagination, which is a tactic of human thinking in exploring the laws and essences of mathematics. Conjecture plays an important role in mathematics teaching. Combining the teaching design of the sixth unit of the 86th page of the sixth edition of the “Elementary School Suiyu Edition” with “1089” mathematics review questions, the teaching of mathematical guess strategy Practice, and how to guide students to make reasonable conjectures, to carry out the relevant exploration, verification, questioning, reflection.
