Objectives

By the end of this lesson, students will be able to:

• Understand the concepts of mass, grams, and kilograms.
• Read and interpret measurements on a scale.
• Compare different masses using grams and kilograms.

---

Materials Needed

• Bathroom scale or balance scales (one for demonstration)
• Weights (various objects, some in grams and some in kilograms)
• Worksheets for practice
• Whiteboard and markers
• Measuring scales images (for visual reference)

Lesson Structure

Introduction (5 minutes)

1. Engage the Students:

   • Begin with a question: "What do you think mass means? Can you give examples of things we can weigh?"
   • Allow students to share their thoughts.

2. Introduce Key Vocabulary:

   • Define mass, grams, kilograms, and scales.
   • Show a picture of a scale and discuss its parts (display, readout).

Direct Instruction (10 minutes)

1. Mass Units:

   • Explain that mass is the amount of matter in an object, measured in grams and kilograms.
   • Illustrate the difference:
     • 1000 grams = 1 kilogram.
     • Use familiar examples (e.g., a small apple weighs about 150 grams, while a bag of flour might weigh 1 kilogram).

2. Reading Scales:

   • Demonstrate how to use a scale.
   • Place different items on the scale, read their mass aloud, and discuss if the mass is in grams or kilograms.
   • Show how to convert between grams and kilograms, giving simple examples (e.g., “If I have 2000 grams, how many kilograms is that?”).

Guided Practice (5 minutes)

1. Interactive Activity:
   • Have students gather around the scale.
   • Invite them to weigh objects provided and record their mass on the whiteboard.
   • Ask guiding questions, such as: "Is that more or less than 1 kilogram?"

Independent Practice (5 minutes)

1. Worksheets:
   • Distribute worksheets with problems that ask students to convert grams to kilograms and vice versa, and to read scales based on provided images.
   • Include a few word problems, such as "If you have 500 grams of sugar and you need a total of 2 kilograms, how much more do you need?"

Closing (5 minutes)

1. Review and Recap:

   • Ask students what they learned about mass measurement.
   • Reinforce the connection between grams and kilograms.

2. Q&A Session:

   • Open the floor for any questions or clarifications.
   • Ensure all students grasp the concepts covered in the lesson.

Assessment

Students will be assessed based on:

• Participation during the interactive activities.
• Accuracy in the worksheets.
• Ability to explain their thought process when reading scales and converting measurements.

---

Extensions

• For advanced students, provide more complex problems involving addition and subtraction of masses.
• For students needing extra support, offer hands-on practice with additional items for weighing and converting.
