2. Content

Measure the lengths of objects using customary units. Convert lengths
between the different customary units. 


3. Goals: Aims/Outcomes

1. Students will measure items to either the nearest inch, foot,
or yard.
2.Students will estimate the length of items to the nearest inch,
foot, or yard.
3. Students will convert their measurements to different customary
units of length. 


4. Objectives

Students will be able to...
1. measure and estimate lengths.
2. understand the difference between estimating and measuring.
3. convert measurements to different customary units of length. 


5. Materials and Aids

SMART Board, whiteboard, rulers, yardsticks, pencils Scavenger Hunt
Worksheet, and Line Segments and Measure Worksheet 


6. Procedures/Methods

A. Introduction
Students will measure line segments with rulers (worksheet) 


B. Development
The teacher will start off by giving the answers to the Introduction
activity ("Do Now") and reviewing how to properly measure line segments.
The teacher will teach the students benchmarks that can be used to
make effective estimates. To make sure the students are grasping the
concept of estimation, the teacher will point to different objects
in the classroom and ask them to estimate its length. The teacher
will then go over the customary units of length (inch, foot, yard,
mile) and their conversion factors. Examples will be done as a class
to evaluate how well students can convert units. The teacher will
lead the discussion in how one determines which unit should be used
to measure an object. The students will be put in pairs and given
the Measurement Scavenger Hunt Worksheet and directed on how they
should complete the activity. Once the students finish, the teacher
will lead the class in comparing the groups' measurements. The students
will next be given a worksheet that asks conceptual questions as well
as conversions. This will be collected to assess the students' understanding. 


C. Practice
The class as whole will complete conversation examples together. 


D. Independent Practice
Students will be put in pairs and instructed to complete the Measurement
Scavenger Hunt Activity. The teacher will checkup on the different
pairs to make sure that they are on task and understand what is asked
of them and how to complete the activity. 


E. Accommodations (Differentiated Instruction)
None needed for this activity. 


F. Checking for understanding
Distribute a worksheet that evaluates the students' comprehension
of main ideas and ability to convert units. 


G. Closure
Discuss careers that depend on measuring and estimating lengths.
