Introduce how to use standard and metric units of measure to measure length with our Measuring Length Lesson Plan. This interactive lesson engages students with practical applications of determining length. Generalize and solidify understanding as students measure each other’s heights and order themselves from shortest to tallest.
Sample Classroom Procedure / Teacher Instruction
- Display the following ahead of time: Average Height of a Woman-5’ 4”, of a Man-5’ 9 ½ “. Distance from (your town to another town)- ??.
- Ask: Why do we sometimes need to know the length of an object, or the distance between places?
- Allow for responses and discussion. Introduce measuring length by asking students if they know how tall they are.
- Allow students to share their answers.
- Record some of their heights.
- Emphasize the difference in using inches/feet versus centimeters/meters.
- Distribute Measuring Length content pages. Read and review the information with the students. Use additional examples as needed for student understanding.
- Distribute Activity page. Review the instructions.
- You may tell students to measure the longest part of an item to ensure consistency with students. (Measuring length only, not width, thickness, etc.)
- Give students ample time to measure each of the numbered items in the classroom. (You must tell students to round to the nearest inch or half inch before beginning.)
- Once students are completed with the activity, review the responses. Give each pair of students an opportunity to share.
- Distribute the Practice page. You may permit students to use a ruler to measure each line. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses. Use additional resources if necessary to supplement students’ understanding of measuring length.
- In closing, pair students and allow them to measure each other’s heights in inches and in centimeters. Tell them to record their height on a piece of paper.
- Place students in a line from smallest to tallest. Once in a line, ask students to share their heights aloud and they should be in order. (Some students may need to re-measure themselves.)
