Students will be able to recognize the units of measurement of length (km, m, cm, mm).
Students will demonstrate their understanding of converting one unit of measurement to another.
Students will be able to use appropriate units of measurement in real-life situations.
Materials:
Whiteboard and markers
Ruler
Measuring tape
Worksheets for practice
Procedure:
Introduction (5 minutes):
Teacher will write the names of the units of measurement of length on the board (km, m, cm, mm) and ask students if they know what they mean.
Teacher will define each unit of measurement and explain that they are used to measure length.
Teacher will ask students if they have ever measured something before, and if they used any of these units of measurement.
Main Activity (20 minutes):
Teacher will demonstrate how to convert one unit of measurement to another, using a ruler and measuring tape.
Teacher will ask students to work in pairs or small groups to measure objects in the classroom using the ruler and measuring tape.
Students will record their measurements in both centimeters and millimeters.
Students will be asked to convert their measurements to meters and kilometers.
Teacher will discuss the different contexts in which each unit of measurement is used (for example, kilometers for long distances, centimeters for small objects).
Practice (5 minutes):
Teacher will provide worksheets for students to practice converting units of measurement.
Homework (5 minutes):
Students will be assigned to measure objects at home using a ruler and measuring tape.
They will write down their measurements in both centimeters and millimeters, and convert them to meters and kilometers.
Students will share what they have learned with their classmates during the next lesson.
Conclusion:
In this lesson, students learned about the different units of measurement of length, how to convert one unit to another, and when each unit is used. They also had the opportunity to practice measuring objects using a ruler and measuring tape, and to apply their understanding of units of measurement to real-life situations.
