一、在引入中体现通过课本中的情境图(如图1)让学生明白,要知道两个花坛的面积哪个大,就必须计算出它们的面积,学习平行四边形面积的计算方法是生活实际的需要。从而增强学生学好数学的信心,让学生领悟到数学的价值,体现课程标准中人人学有价值的数学的基本理念和数学与生活实际相结合的要求。
First, introduced in the introduction of textbooks through the context map (Figure 1) to let students understand that to know which of the two flower beds area, it is necessary to calculate their area, learning parallelogram area is calculated by the actual life need. So as to enhance students’ confidence in learning mathematics and make students realize the value of mathematics, embody the basic concepts of mathematics valuable to all in human learning and the requirements of combining mathematics with the actual life.
