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}

Lesson plan

Topic

Part-Whole Models

Objectives

• Understand the concept of part-whole relationships in mathematics.
• Develop the ability to represent numbers using part-whole models.
• Solve simple addition and subtraction problems using part-whole models.

Materials

• Whiteboard and markers
• Part-whole model diagrams (printed or drawn)
• Counters (e.g., small blocks, buttons)
• Worksheets with part-whole problems
• Homework assignment sheets

Grade or Age Group

Year 1

Subject

Mathematics

Class Size

20 Students

National Curriculum Reference

This lesson aligns with the UK National Curriculum for Mathematics, focusing on addition and subtraction within 20 and using concrete objects to support understanding.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction to Part-Whole Models	5	Explain what part-whole models are using visual aids. Introduce terms 'part' and 'whole'.
2	Demonstration	10	Show how to use counters to create a part-whole model. For example, if the whole is 5, show different combinations of parts (2 and 3, 1 and 4).
3	Guided Practice	7	In pairs, students create their own part-whole models using counters while the teacher circulates to assist.
4	Independent Practice	5	Distribute worksheets for students to complete part-whole problems independently.
5	Feedback and Homework	3	Collect worksheets, provide quick feedback, and distribute homework assignments focusing on part-whole models without students presenting in front of the class.

Homework

• Complete a worksheet on part-whole models with a focus on addition and subtraction using counters at home.
• Practice making part-whole models with everyday items around the house (e.g., fruits, toys).

Assessment

• Monitor students’ understanding during guided practice.
• Review completed worksheets for correctness in application of part-whole models.
• Collect feedback on homework to assess understanding and progress.
