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: Partitioning 2-Digit Numbers

Subject

Mathematics

Topic

Partitioning 2-Digit Numbers

Grade/Age Group

Year 1

Length of Lesson

30 minutes

Number of Students

Objectives

Students will understand the concept of partitioning 2-digit numbers into tens and ones.
Students will demonstrate their ability to partition numbers using visual aids and manipulatives.
Students will apply partitioning in problem-solving scenarios.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Engage students with a question about their favorite 2-digit numbers. Introduce partitioning by explaining tens and ones.
2	Demonstration	10	Use Base Ten blocks to show how to partition a number like 34 into 30 (3 tens) and 4 (4 ones). Encourage students to ask questions.
3	Guided Practice	5	Distribute Base Ten blocks and ask students to partition different 2-digit numbers in pairs, such as 56 and 82. Monitor their progress.
4	Independent Practice	7	Hand out worksheets where students will partition given 2-digit numbers independently. Provide support as needed.
5	Homework Explanation	2	Explain homework assignments which will include partitioning practice. Ensure students understand what is expected.
6	Closure	1	Recap the lesson by asking students to share one thing they learned about partitioning. Collect worksheets for review without asking students to present.

Assessment

Observation of student participation during guided and independent practice.
Review the completed worksheets to assess understanding of the partitioning concept.
Feedback will be provided on homework assignments the following lesson.

Homework

Assign students a worksheet for further practice on partitioning different 2-digit numbers, which they will complete at home.
Students will submit the homework in the next class without presenting in front of their peers.

National Curriculum Alignment

This lesson aligns with the Australian Curriculum's Mathematics content descriptions for Year 1, specifically focusing on the understanding of place value and the partitioning of numbers.

This lesson plan is designed to be engaging and interactive, catering to various learning styles while adhering to Australian education standards.
