Lesson Plan: Measurement
Grade Level: 2
Duration: 30 Minutes
Subject: Mathematics
Objective
By the end of this lesson, students will be able to:
- Understand the concept of measurement.
- Use non-standard units (e.g., paper clips, blocks) to measure objects.
- Compare the lengths of different objects.
Materials Needed
- Paper clips (or other non-standard measurement units)
- Rulers (optional)
- Various classroom objects (e.g., pencils, books, erasers)
- Whiteboard and markers
- Measurement Worksheet (with empty spaces for students to fill in measurements)
Introduction (5 Minutes)
-
Warm-Up Question:
- Begin by asking students: "What is measurement?" Encourage a brief discussion to gather responses.
- Explain that measurement helps us understand the size of things.
-
Introduction to Non-Standard Units:
- Show students paper clips or blocks and explain that these are non-standard measurement tools we can use to measure objects in our classroom.
Direct Instruction (10 Minutes)
-
Demonstration:
- Choose a classroom object (e.g., a pencil) and demonstrate how to measure its length using paper clips:
- Line up the paper clips next to the pencil without overlapping.
- Count how many paper clips long the pencil is.
-
Guided Practice:
- Have students practice measuring the length of another object (e.g., a book) using their own paper clips.
- Walk around the classroom to provide support and check for understanding.
Independent Practice (10 Minutes)
-
Measurement Activity:
- Distribute the Measurement Worksheet to each student.
- Instruct students to measure the lengths of three different classroom objects using paper clips and record their findings on the worksheet.
- Encourage them to choose objects that are different sizes.
-
Encourage Comparison:
- Ask students to compare the lengths of the objects they measured in pairs and discuss who used more or fewer paper clips.
Closing (5 Minutes)
-
Review:
- As a class, discuss the measurements collected. Ask questions such as:
- "Which object was longest?"
- "How many paper clips did you use for each object?"
-
Conclusion:
- Reinforce the idea that we can measure things in different ways and that measurement can help us compare and describe objects.
-
Exit Ticket:
- Ask students to write down one thing they learned about measurement today and share it with the class as they exit.
Assessment
- Observe students during the measuring activity to assess their ability to measure and compare lengths.
- Review the completed Measurement Worksheets to evaluate understanding of using non-standard units for measurement.
Extensions
- For students who finish early, provide additional objects to measure or challenge them to find objects in the classroom that are longer or shorter than their own measurements.
Modifications
- For students needing additional support, pair them with a partner to measure objects together.
- For advanced students, introduce the concept of standard measurement units (inches, centimeters) with rulers for future lessons.
By following this lesson plan, students will gain a foundational understanding of measurement, which is essential as they advance in mathematics.
