小学数学长作业是以小学数学学科为基础,将数学知识和现实生活相结合,以小学生兴趣为导向,强调数学知识在现实生活中的运用,需要学生花费一定时间探究才能完成的多样性作业。小学数学长作业的特点——时间比较长、形式多样化、主题有趣味、内容探究化。数学长作业的实施包括数学小课题研究的实施;数学手抄报的实施;数学周记的实施等。数学长作业使封闭的书本文化积累过程转变为开放的、活生生的与社会紧密相连的自主创新过程,让学生对数学产生浓厚的兴趣,进而促进学生数学素养的真正提高。 Primary school mathematics is based on primary school mathematics, based on the combination of mathematical knowledge and real life, primary school students interest oriented, emphasizing the use of mathematical knowledge in real life, requires students to spend some time to explore the diversity of operations can be completed. The characteristics of primary school mathematics long assignments - time is long, the form is diversified, the theme is interesting, the content explores. The implementation of math long assignments includes the implementation of small maths research; the implementation of mathematical hand-copied newspapers; the implementation of mathematical weekly notes. The long work of mathematics has transformed the closed process of book culture into an open and living process of independent innovation closely connected with society. Students are expected to have a strong interest in mathematics and thus promote the true improvement of students’ mathematical literacy.
