引人入胜的减法算法教学演示。
Use this animated PowerPoint with your students when learning how to use the减法algorithm and borrowing.
借款减法
通过借贷/重组教学垂直减法可能是一个挑战。该教学演讲旨在通过使用对话语调来简化过程。您可以通过阅读文本来叙述每个步骤，屏幕上的视觉效果将匹配。
演讲始于使用混凝土材料（即基本10块）借贷的解释，以帮助可视化相当抽象的概念。通过让学生使用物理块重复此内容，然后使用自己选择的数字来扩展演示文稿的这一部分。
Nothing to Borrow?
The teaching presentation also has a section describing what to do when a neighboring column has nothing to borrow. You could complete this section at the same time as the first or separate these parts over two lessons to ensure your students grasp the concept of traditional borrowing before moving on to ‘double borrowing’.
