为培养学生学习'珠井的兴趣,提高珠算加法和乘法的计葬能力,教师可在学生学完珠算乘去以后,组织一堂以“超味珠算”为题的课外数学课。现将其教学过程设计简述如下。 1、简述珠算发展史和我国明代的珠算大师程大位的生平。珠算是我国劳动人民在数学方面的重大发明。公元1274年,我国宋朝数学家杨辉在他所著《乘除通变其宝》一书中,就有珠算歌诀的记成。公元1366年,我国元朝数学家峋宗义所若《南村极拼录》一书中,也记成有'葬盘珠,一词,并说明'援之则动,。
In order to cultivate students' interest in studying and enriching abacus and abacus, teachers can organize extracurricular math classes entitled “Beyond Abacus” after students learn abacus and multiply. Now the teaching process design is as follows. 1, a brief account of the history of abacus and abacus master Cheng Dawei's life in Ming Dynasty. Abacus is a major invention of our working people in mathematics. In 1274 AD, Yang Hui, a mathematician of the Song Dynasty in our country, wrote a book titled “Adoption of Divination and Transformation”. In 1366 AD, the poet Yu Zongyi of the Yuan Dynasty in our country wrote a book titled “Purnishing Panzhu” in his book, “Nancun Jiju Lu”.
