MEASURING
OURSELVES
The target grade for this lesson plan is the fifth grade (ages 10-11). Fifth graders are just beginning to enter puberty so there is a physical variety (height, deepness of voice, weight, etc.) among the students due to the difference in rates of reaching puberty. They feel a sense of maturity, being the oldest students in the elementary school. They may also seem anxious and excited about entering middle school and experiencing more independence that comes along with it (walking to and from different classrooms, owning a locker, etc.). They seem to enjoy any independence granted, even in class work. Cognitively, 5th graders are at the beginning of the formal operation stage, which means that they are starting to solve abstract and hypothetical problems and think combinatorially, sometimes without the aid of concrete examples. In terms of social and personal development, fifth graders are developing a sense of industry; enjoying mastery and competence through success and recognition of accomplishment. However, they may feel a sense of inferiority if challenges are too difficult or if accomplishments seem easy and trivial. Also, friendships seem to take on more significance, as indicated by the formation of cliques or tight knit groups of friends. These relationships have an impact in the students’ school and home lives. The lesson will cater to the fifth graders’ developmental needs, especially in the area of independence and industry. The students will be working independently (not as individuals, but with freedom and flexibility) and their accomplishments will be recognized concretely by the use of graphs and charts in the Excel program. Also, relational emphasis is added by the application of group work.
Objectives
5.11 The student will choose an appropriate measuring device and unit of measure to solve problems involving: measurement of length-part of an inch (1/2, 1/4, and 1/8), inches, feet, yards, miles, millimeters, centimeters, meters, and kilometers; weight/mass-ounces, pounds, tons, grams, and kilograms; temperature-Celsius and Fahrenheit units. ObjectivesWorking with a partner, students will measure their heights to the 1/8 of an inch with the use of a measuring tape. Working with a partner, students will measure their weight on a bathroom scale estimated to the nearest pound. Working with a partner, students will measure the thumb-to-pinky span to the 1/8 of an inch using a standard wooden 12-inch ruler. Working with a partner, students will measure their body temperatures using a thermometer placed into their armpits. Given the data of entire class, students will correctly type in data onto an Excel worksheet, including appropriately indicated column headings. (body temperature, height, etc.) Given the class data on an Excel spreadsheet, students will convert the data into 3 graphs for the different body measurements; bar for thumb-pinky span and height, line for weight, and pie for body temperature. Students will be able to distinguish between a pie chart, bar graph, and line graphs. Students will be able to notice trends and patterns by observing class data presented on different types of graphs.
Materials
Computer lab with Excel program on each computer (enough computers for all pairs of students in class)
Projector that presents the computer screen onto an overhead screen
Tape measure for each student pair for measuring height
12-inch ruler for each student pair for measuring hand span
5 bathroom scales (for the class to share) for measuring weight (ask for volunteers to bring from home)
Thermometer for each student pair for measuring body temperature
Worksheet (How Do You Measure Up?)

Evaluation Procedure
Class work review: Student pairs’ spreadsheets and graphs will be retrieved and reviewed. If assignment was done correctly, students’ spreadsheet and graph should resemble those of the teacher’s.
