Title of Book: How Tall, How Short, How Faraway Author: David A. Adler Publisher: Holiday House ISDN: 0-8234-1375-6 Grade Levels for Recommendation Use: 3rd – 5th grade TEKS: 3rd grade (9) Geometry and measurement. The student applies mathematical process standards to select and use units to describe length, area, and time. The student is expected to: (A) find the length of objects using concrete models for standard units of length; (B) describe the inverse relationship between the size of the unit and the number of units needed to equal the length of an object; (D) determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes; Summary: This book illustrates several measuring systems, for example the Egyptian system (cubits, palm, and digits) , standard system (inches, yards, feet) and the metric system (centimeters, meter, kilometer). Student Objectives Demonstrate the basic measures of length, and height by measuring objects and recording the information. Materials Yarn Ruler Tape measure Yardstick Classroom objects to be measured (pencil, box, book, desk, etc.). Be sure the objects can be easily measured with the tools you are using. Procedures 1. Display a ruler, yardstick, tape measure. Explain to students that these tools are used to measure. The ruler, tape measure, and yardstick are tools for measuring the length, and height of an object. Model how to use these tools by lining up the end of an object with the end of the tool and identifying the nearest inch as the length, or height. Set up two stations for students to practice measuring length, and height. 2. o o Station 1- Place several classroom objects and the ruler, tape measure, and yardstick at the station. First have students measure self and each object using the Egyptian system. Next, have the students take turns using the measuring tools to find the length, and height of each object using the standard system. They should record their measurements in Chart 1 Measuring the Length and Height of Objects. Then they can compare and discuss measurements. Station 2- Place several classroom objects and the ruler, tape measure, and yardstick at the station. First have students measure self and each object using the Egyptian system. Next, have the students take turns using the measuring tools to find the length, and height of each object using the standard system. They should record their measurements in Chart 1 Measuring the Length and Height of Objects. Then they can compare and discuss measurements. The students' abilities will determine the amount of guidance and support needed at each station. For very young students one or two objects to measure are sufficient. As an extension students can go outside and find the length, and height of larger objects. They can find the perimeter of the playground, the length of the slide, or draw large boxes with sidewalk chalk and measure the length and height. Assessment Use the following three-point rubric to evaluate students' work during this lesson. 3 points: Students produced complete charts, including all the requested information; clearly demonstrated the ability to measure length, height. 2 points: Students produced adequate charts, including most of the requested information; satisfactorily demonstrated the ability to measure length, height. 1 point: Students produced incomplete charts with little or none of the requested information; did not demonstrate the ability to measure length, height. Vocabulary Ruler Definition: A straight strip of material (plastic, wood, or metal) marked off in units and used for measuring Tape measure Definition: A tape (metal or cloth) marked off in units and used for measuring Yardstick Definition: A measuring stick that is one yard, or three feet, or 36 inches long References and Websites: National Council of Teachers of Mathematics (NCTM) has developed national standards to provide guidelines for teaching mathematics.
