Lesson Plan : Measuring With A Metric Ruler

Teacher Name:
 Dr. Trainer
Grade:
 Grade 7-8
Subject:
 Vocational Ed.

Topic:
 Measurement using ruler and metric ruler
Content:
 Math concepts related to engineering, manufacturing, and construction processes and technology. Estimating, rounding, precise, fractions of an inch, standard ruler, metric ruler, metric and standard measurements
Goals:
 Students will be able to demonstrate an understanding of the role of measurement in engineering, manufacturing, and construction processes and technology.
Objectives:
 Students should be able to understand and use a standard and metric ruler to take measurements.
Materials:
 PowerPoint presentation,standard ruler, metric ruler, measuring tape, pencil, worksheets, objects to measure, paper, string, and tape
Introduction:
 Students will complete a K-W-L chart by writing what they already know about measurement, what the want to learn, and then upon completing the unit, what they learned. A video will be shown on the history of measurement.
Development:
 Teacher will show a standard ruler, metric rules, and measuring tape to the class. A basic, simple measurement will be demonstrated. The difference between a metric and standard ruler will be explained. After each unit of measurement, a worksheet will be given to measure that particular unit of measurement. Ex. sixteenth of an inch, quarter of an inch, millimeter, etc.
Practice:
 Students, using rulers, will measure specific measurements using the worksheets provided. The teacher will allow students to work in pairs and she will monitor the activity as the students work. Students will measure one line at a time and the teacher will allow student responses and check answers following each measurement. This will identify who is measuring incorrectly pretty quickly. Students will then shown how to lay the string along objects that are difficult to measure with a ruler, and then measure the string. Then they will be shown how much easier it is to use a tape measure. (someone will probably recognize this on their own!)
Accommodations:
 Peer partners and/or easier or fewer measurements will be provided to those needing modified assignments.
Checking For Understanding:
 A drawing created by drawing measured lines will be assigned. If the outcome is a complete drawing, then the measurements were done correctly. If the picture makes no sense, there were errors in the measurements.
Closure:
 A class discussion on the importance of measuring correctly will follow. (If you don't follow the measurements exactly, you don't see the true picture!)
Evaluation:
 Students will create their own drawing, recording the measurement statistics for each line in their drawings. They will exchange theirs with a partner's and complete the drawing.
