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}

Subject

Mathematics

Materials

• Whiteboard and markers
• Part-part-whole model visual aids (e.g., charts or worksheets)
• Counters or manipulative objects (e.g., blocks)
• Worksheets for guided and independent practice
• Homework sheets

20 students

Length of Lesson

30 minutes

National Curriculum Alignment

This lesson aligns with the Australian Mathematics Curriculum for early numeracy, focusing on addition and subtraction within the context of part-part-whole models.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 minutes	Introduce the part-part-whole model using visual aids. Explain its usefulness in solving addition and subtraction problems. Highlight the connection to real-life situations.
2	Guided Practice	10 minutes	Use counters to demonstrate the part-part-whole strategy. Solve a couple of addition and subtraction examples together as a class, encouraging students to participate and provide answers.
3	Hands-on Activity	10 minutes	Divide students into pairs. Provide them with counters and worksheets to solve given addition and subtraction problems using the part-part-whole strategy. Monitor and assist as needed.
4	Independent Practice	3 minutes	Distribute independent worksheets for students to complete individual addition and subtraction problems utilizing the part-part-whole model.
5	Closing & Homework Assignment	2 minutes	Review key concepts from the lesson. Assign homework that reinforces the part-part-whole strategy. Explain that homework will be checked, but students will not present it in class.

Homework

• Complete a worksheet on addition and subtraction problems using the part-part-whole strategy at home. Encourage students to explain the strategy to their family members.

Reflection

• Consider the effectiveness of the lesson based on student engagement and understanding during guided and independent practice. Adjust future lessons based on observed difficulties and successes.
