“解决问题”是数学课程的重要目标之一。解决问题需要相应的策略支撑对问题的分析、思考,让学生了解和形成解决问题的一些基本策略,体验解决问题策略的多样性。利用策略解决问题,可以强化学生学习数学的能力基础,增强解决问题的意识,也有利于学生的可持续发展,所以“解决问题的策略”教学在小学阶段非常重要。在解题策略教学中,适时恰当地选用交互式电子白板来辅助教学,使抽象的数学内容形象化、清晰化,使学生逐步 “Problem solving ” is one of the important goals of the math course. To solve the problem, we need corresponding strategies to support the analysis and thinking of the problems so that the students can understand and form some basic strategies for solving the problems and experience the diversity of strategies for solving the problems. Using strategies to solve problems can strengthen students' abilities to learn math, enhance their awareness of problems, and help students to achieve sustainable development. Therefore, “problem-solving strategies” are very important in primary school. In the problem-solving strategy teaching, timely and appropriate selection of interactive whiteboards to assist teaching so that the abstract mathematical content visualization, clarity, so that students gradually
