1. Topic-
 Measurement
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.
