Objective: - Students will be able to measure and compare the lengths of objects using non-standard units. - Students will be able to estimate and measure the length of objects accurately.
Materials: - Various objects of different lengths (e.g. pencils, rulers, books, etc.) - Non-standard measuring tools (e.g. paper clips, cubes, yarn) - Chart paper - Markers - Worksheets for practice
Introduction (5 minutes): 1. Begin the lesson by asking students if they know what length means. 2. Explain that length is how long something is from one end to the other. 3. Show students different objects of varying lengths and ask them to estimate which object is longer or shorter.
Body (30 minutes): 1. Demonstrate how to measure the length of an object using non-standard units (e.g. using paper clips or cubes). 2. Have students practice measuring the length of different objects using non-standard units. 3. Discuss with students how to compare the lengths of objects and which object is longer or shorter. 4. Provide students with worksheets to practice measuring and comparing lengths independently. 5. Have students work in pairs to measure the length of objects and compare their measurements.
Conclusion (10 minutes): 1. Review the concept of length with students and ask them to share what they have learned. 2. Have students create a chart on chart paper to display the lengths of different objects they measured. 3. Encourage students to continue practicing measuring and comparing lengths in their daily lives.
Assessment: - Observe students as they measure and compare lengths of objects. - Review completed worksheets to assess students' understanding of the concept of length. - Ask students questions to gauge their comprehension of the lesson.

Lesson Plan: Length
Grade Level: 2
Subject: Measurement
Objectives:
- Students will be able to compare and order objects by length using non-standard units of measurement. - Students will be able to use rulers to measure length in inches.
Materials:
- Various objects of different lengths (e.g., pencils, crayons, strings) - Non-standard units of measurement (e.g., paper clips, toothpicks) - Rulers (one per student) - Whiteboard or chart paper - Markers
Procedure:
1. Warm-up (5 minutes)
- Begin by asking students to hold up their hands and compare their heights. - Discuss which student is tallest, shortest, and in the middle.
2. Comparing Objects by Length Using Non-Standard Units (15 minutes)
- Gather various objects of different lengths. - Divide students into groups of 3-4. - Distribute non-standard units of measurement to each group (e.g., paper clips, toothpicks). - Have groups measure the length of the objects using their non-standard units. - Guide groups to compare the lengths of the objects and order them from shortest to longest.
3. Measuring Length with Rulers (15 minutes)
- Introduce rulers as a tool for measuring length. - Demonstrate how to use a ruler by placing it alongside an object and reading the length in inches. - Have students practice measuring the length of various objects using their rulers. - Create a chart on the whiteboard or chart paper to record the measurements of the objects.
4. Ordering Objects by Length (10 minutes)
- Once students have measured the length of the objects, have them work in pairs to compare and order the objects from shortest to longest. - Encourage students to use mathematical language such as "shorter than" and "longer than."
5. Independent Practice (15 minutes)
- Distribute a worksheet with objects of different lengths. - Have students measure the length of the objects using rulers and record their measurements on the worksheet. - Provide assistance as needed.
Assessment:
- Observe students during the activities to assess their understanding of comparing and measuring length. - Collect worksheets to check students' ability to measure length accurately.
Differentiation:
- For struggling students, provide more support during the activities. Use smaller and simpler objects for them to measure. - For advanced students, challenge them by providing objects with fractional lengths (e.g., 1 1/2 inches).
