Today, I will determine the appropriate tool to measure an object in customary units of length.
Vocabulary customary units of length: 1 inch = from about the tip of the thumb to first knuckle (measured using a ruler) 1 foot = 12 inches, from about the elbow to wrist (measured using a ruler) 1 yard = 36 inches or 3 feet, arm span (measured using a yardstick or tape measure)
Teacher Resources Considerations: In first grade, students had the experience of measuring with nonstandard units. Giving second graders the opportunity to create and use a variety of rulers can help them connect their understanding of non-standard units from first grade to standard units in second grade. Make sure students have access to rulers, yardsticks, meter sticks, and tape measures for this unit.
Steps: 1. Determine which measuring tool to use. 2. Align the edge of the object to the edge of the ruler. 3. Follow the object to the point on the ruler where the object ends.
Application of MPs: MP5: What tool did you use to help you solve the problem? MP6: What do you need to do to ensure your answers are correct when measuring? MP7: What concepts or rules helped you determine how to measure each length?

1.
Hold up a pencil and tell the class they will be measuring the length of the pencil using the U.S. Customary System.
Review units of measurement using the chart on the previous page. Discuss with the class which unit(s) would be most appropriate to use.
Model how to pick an appropriate tool. Use the chart to show smaller units (inches) are measured with a ruler. Smaller length tool: Ruler
Model lining up the ruler and starting the measuring at zero to measure the pencil. Measure and record the length in inches.
Point to the teacher’s desk and tell the class you will be measuring the width of your desk using the U.S. Customary System.
Review units of measurement using the chart on the previous page. Discuss which unit(s) would be most appropriate to use.
Model how to pick an appropriate tool. Use the chart to show larger units (yards) are measured with a yardstick or tape measure. Discuss how a tape measure is used to measure a longer length, so the yardstick is a good option.
2.
Medium length tool: Yardstick
Model lining up a yardstick starting the measuring at zero to measure the desk. Measure and record the length in yards.

1.
Supply students with a crayon and tell the class they will be measuring the length of the crayon using the U.S. Customary System. Review units of measurement, inches, feet, and yards. Discuss which unit(s) would be most appropriate to use
Pick an appropriate tool. Use the chart to determine that smaller units (inches) are measured with a ruler. Smaller length tool: Ruler
Line up rulers and start measuring at zero to measure the crayon. Measure and record the length in inches.
Point to the doorway and tell the class they will be measuring the height of the doorway using the U.S. Customary System. Review units of measurement, inches, feet, and yards. Discuss which unit(s) would be most appropriate to use
2.
Medium to Larger length tools: Yardstick/Tape Measure
Pick an appropriate tool. Use the chart to determine that larger units (feet or yards) are measured with a yardstick or measuring tape.
Line up yardsticks and measuring tapes to determine which works better. Start measuring at zero to measure the height. Measure and record the length.

Directions: Solve.
1. Students will determine the best U.S. Customary Unit of measurement to measure the width of their Beyond the Basic Facts notebook. They will use the appropriate tool to measure the width.
2. Students will determine the best U.S. Customary Unit of measurement to measure the width of the white board. They will use the appropriate tool to measure the length.
