Dài và ngắn của một đồ vật, thông qua bài học này học sinh được giới thiệu về sắp xếp độ dài, học sinh có khả năng so sánh độ dài các đồ vật và sử dụng thuật ngữ dài nhất ngắn nhất. The long and the short of it….. In this introductory lesson to ordering lengths, students will be able to compare objects by length using the vocabulary longest and shortest.Ý tưởng về dài hơn ngắn hơn sử dụng các đồ vật thực tế trong thế giới thực (cuộc sống hằng ngày). It gives the students the idea of longer, taller, and shorter using real world objects. If this book isn't available, there are many other books about measuring that will get the students engaged and excited about the lesson. The idea is to get students to apply measuring to real world applications and get their minds thinking about what they already know about measuring. After reading the book, I randomly call on three or four students and have them line themselves up from shortest to tallest. I don’t guide them; I allow them to discover how to determine who is the tallest and who is the shortest. I continue to call up a few students at a time and have them join in on the line. After all students are lined up, I ask how they decided who was taller and who was shorter.
