Lesson Plan: Measure in cm
Subject: Mathematics
Grade: Year 2
Duration: 30 minutes
Topic: Measure in cm
Lesson Objectives
By the end of this lesson, students will be able to:
- Understand the concept of measurement in centimetres.
- Use a ruler to measure objects accurately.
- Compare lengths of different objects using measurement in cm.
Required Materials
- Rulers (cm)
- Various classroom objects to measure (e.g. pencils, books, erasers)
- Measurement worksheets
- Whiteboard and markers
Introduction (5 minutes)
- Begin the lesson by discussing the importance of measuring objects.
- Ask the students why they think measuring is important in everyday life.
- Introduce the centimetre as a unit of measurement, explaining how it is used for measuring length.
Direct Instruction (10 minutes)
-
Demonstration:
- Show the students how to use a ruler to measure the length of an object.
- Use a pencil and demonstrate placing the ruler at the beginning of the object and noting the measurement.
-
Key Vocabulary:
- Length
- Centimetre (cm)
- Ruler
- Measure
-
Measurement of Objects:
- Provide a few examples of everyday objects and ask the students to predict their lengths in cm before measuring.
Guided Practice (10 minutes)
- Have the students pair up and choose 3 different objects from their desks to measure.
- Instruct them to measure each object in centimetres using their rulers.
- As they measure, encourage them to share their findings with their partner and discuss any differences in their measurements.
Independent Practice (5 minutes)
- Distribute measurement worksheets that include pictures of various objects and empty lines for students to fill in the measurements.
- Ask them to measure the objects on the worksheet in centimetres and write the correct measurements next to each item.
Conclusion (5 minutes)
- Gather the students’ attention and review what they learned about measuring in cm.
- Ask a few students to share their findings from the worksheet.
- Reinforce the importance of accurate measuring and how it applies to various real-life scenarios.
- Announce that in the next lesson, they will practice measuring longer objects and using addition to compare lengths.
Assessment
- Collect the measurement worksheets to assess the students' understanding of measuring in centimetres.
- Observe students during guided practice for engagement and correct measuring techniques.
Homework
- Ask students to find three objects at home and measure them in centimetres, writing down their measurements to share in the next class.
