【Abstract】The education industry is actively promoting the reform of subject teaching. The mathematics curriculum standard has assigned new tasks to teachers' teaching, requiring primary school mathematics teachers to pay attention to the cultivation of students' thinking ability. Primary school mathematics teaching should not only allow students to master systematic mathematics knowledge, but more importantly, allow students to develop good study habits and ways of thinking. The most important question for primary school mathematics teachers to think about is what kind of teaching strategies can be implemented to help students develop excellent mathematical thinking skills.

一、提出問题,调动思维
要想调动学生的思维能力,就必须让学生对数学学习产生兴趣,促使学生积极主动地发散思维、思考问题。小学生学习积极性均取决于教学活动的趣味程度,兴趣是激发学生思维能力的基础条件。常见的调动学生思维的方式包括,从教学内容出发,教师提出趣味性问题引入课堂,让学生思维全程跟随教师步伐。以“圆的认识”教学为例,教学目标为让学生掌握圆周长、面积等多个计算公式。若是直接向学生讲述公式并要求学生背诵,那么学生就无法获得主动思考的机会,其思维能力也无法得到提升。所以教学期间教师可通过设问方式引入课堂:“同学们,以前都是老师向你们提问,今天由你们做老师。你们可以自行搜集各种直径不同的圆,然后告诉老师圆的直径,询问老师该圆的周长,看老师回答得是否正确。”这样的提问形式极具趣味性,学生迫不及待地想要“反客为主”,争先恐后地向教师提问。……
