Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Mass

Objectives

• Understand the concept of mass and its measurement.
• Identify and compare the mass of various objects.
• Use standard and non-standard units to measure mass.

Materials

• Scale (balance scale preferred)
• Various objects of different masses (e.g., fruit, school supplies)
• Measuring scales (in grams and kilograms)
• Non-standard units (e.g., blocks, cups)
• Worksheet for recording measurements
• Whiteboard and markers

National Curriculum Compliance

This lesson aligns with the Australian Curriculum: Mathematics, particularly in the areas of Measurement and Geometry.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 minutes	Introduce the concept of mass. Discuss everyday examples and the importance of measuring mass.
2	Explanation	5 minutes	Explain the difference between mass and weight. Introduce standard (grams, kilograms) and non-standard units.
3	Demonstration	5 minutes	Demonstrate how to use the balance scale with different objects, showing how to measure and compare mass.
4	Guided Practice	10 minutes	In groups, students will use the balance scale and various objects to measure and record their masses on a worksheet providing guidance as needed.
5	Review and Discuss	3 minutes	Gather students for a short discussion on what they learned from their measurements. Ask guiding questions.
6	Conclusion	2 minutes	Summarize the lesson, reiterate key concepts, and introduce homework.

Homework

• Provide students with a worksheet to measure the mass of three items at home using both standard and non-standard units. They will record their observations and findings without needing to present them in class. This promotes self-assessment and understanding of the concept.

Additional Notes

• Ensure all students understand the safety rules when handling scales and objects.
• Adapt instruction as needed for diverse learning needs within the classroom.
• Consider using visuals or props to support learning, particularly for those who may benefit from hands-on activities.
