Grade 2 Mathematics Lesson Plan: Measurement

Grade 2 Mathematics Lesson Plan: Measuring Mass

Materials Needed:

  • Scales (both balance and digital)
  • Various objects for measuring (e.g., books, small toys, fruits)
  • Worksheets
  • Poster paper and markers
  • Interactive whiteboard or projector
  • Dried beans or similar items for non-standard units of measure

Learning Objectives:

By the end of the lesson, students will be able to:
1. Understand the concept of mass.
2. Measure mass using both standard (grams/kilograms) and non-standard units.
3. Compare the mass of different objects.

Vocabulary:

  1. Mass – The amount of matter in an object.
  2. Balance – A tool used to measure the mass of objects.
  3. Scale – A device to measure weight or mass.
  4. Gram – A metric unit of mass.
  5. Kilogram – A larger metric unit of mass (1000 grams).

Previous Learning:

Students have previously identified and compared the lengths of different objects. They are familiar with the concept of measuring in non-standard units (like hand spans).

Anticipated Challenges and Solutions:

  • Challenge: Difficulty understanding the difference between weight and mass.
    Solution: Provide simple, practical examples and consistently use the term “mass”.

  • Challenge: Reading numbers on a scale (especially digital).
    Solution: Provide guided practice with examples and offer additional support for students who need it.

Beginning Activities (5 minutes):

  1. Introduction: Begin with a brief discussion on what mass is. Show students a few objects and ask, “Which one looks heavier?”
  2. Objective Sharing: Explain today’s objectives clearly.

Middle Activities (32 minutes):

  1. Direct Instruction (10 minutes):
  2. Demonstrate how to use a balance scale and a digital scale.
  3. Explain and show the differences between standard units (grams/kilograms) and non-standard units (like using beans).

  4. Guided Practice (12 minutes):

  5. Divide students into small groups.
  6. Provide various objects and have each group measure and record the mass using both non-standard and standard units.
  7. Walk around and provide assistance and feedback.

  8. Independent Practice (10 minutes):

  9. Each student completes a worksheet where they predict, measure, and record the mass of different classroom objects.
  10. Worksheet includes drawing or writing down the mass of objects in grams and non-standard units.

End Activities (3 minutes):

  1. Consolidation: Ask students to share one object they measured and its mass in both standard and non-standard units.
  2. Exit Ticket: Students write or draw one thing they learned about measuring mass today and hand it in as they leave.

Assessment and Checks for Understanding:

  • Observational assessment during guided and independent practice.
  • Completed worksheets.
  • Exit tickets to gauge immediate understanding.

Differentiation Strategies for Diverse Learners:

  • For struggling students: Provide objects that are clearly different in mass and offer one-on-one support during activities.
  • For advanced students: Introduce more complex objects with mass in kilograms and encourage them to explain the differences between the measurements.

Teaching Notes:

  • Emphasise hands-on learning to make abstract concepts more concrete.
  • Encourage collaboration and discussion among students to enhance peer learning.
  • Ensure all worksheets and materials are accessible and adjustable for students with disabilities (e.g., larger print sizes, audio descriptions).

Additional Tips:

  • Use everyday language to describe mass and measurements to make the content relatable.
  • Reinforce learning with visual aids, such as diagrams on the whiteboard.

By adhering to this lesson plan, you will effectively teach Grade 2 students to understand and measure mass, aligning well with CAPS curriculum standards.
