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

2-Digit Partitioning

Objectives

• Understand the concept of partitioning two-digit numbers.
• Develop strategies for breaking down numbers into tens and ones.
• Practice partitioning with various examples to enhance understanding.

Materials

• Whiteboard and markers
• Base ten blocks (tens and ones)
• Worksheets with partitioning exercises
• Number line displayed in the classroom
• Interactive maths games (optional)

Grade/Age Group

Year 1 (Ages 6-7)

Subject

Mathematics

Class Size

20 Students

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Introduce the concept of 2-digit partitioning using real-life examples. Discuss tens and ones.
2	Demonstration	10	Use base ten blocks to demonstrate how to partition a 2-digit number (e.g., 34 = 3 tens and 4 ones). Show on the whiteboard.
3	Guided Practice	10	Provide students with practice problems on the whiteboard. Have them come up and model partitioning with base ten blocks.
4	Independent Practice	5	Hand out worksheets for students to work on partitioning 2-digit numbers independently.
5	Review & Homework Assignment	5	Summarize the lesson by reviewing key points. Assign homework (partitioning exercises) and explain how they should complete it.

Assessment

• Observe students during guided and independent practice for understanding.
• Collect worksheets at the end of the lesson to assess comprehension of partitioning.

Homework

• Partition 5 different 2-digit numbers into tens and ones on a worksheet.
• Homework will be checked for completion without requiring students to present in front of the class.

National Curriculum Alignment

This lesson aligns with the Australian Curriculum for Mathematics, ensuring that students develop a strong foundation in number and place value, specifically in partitioning numbers into tens and ones.

Additional Notes

• Be prepared to offer additional support for students who may struggle with the concept.
• Encourage students to use number lines or counting strategies if needed.
