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}

National Curriculum Compliance

The lesson plan is designed to align with UK National Curriculum goals for mathematics, focusing on number theory and factors.

Lesson Structure

Step Number	Step Title	Length (mins)	Details
1	Introduction	5	Briefly introduce the concept of factors. Ask students what they know about factors.
2	Explanation	10	Define common factors clearly. Use examples (e.g., factors of 12 and 16: 1, 2, and 4).
3	Guided Practice	5	Solve a couple of examples as a class. Students participate in finding common factors.
4	Group Activity	5	Divide students into small groups. Give each group a list of numbers to find common factors.
5	Independent Practice	3	Distribute worksheets with problems on common factors for each student.
6	Assessment and Wrap-up	2	Review answers as a class. Discuss what they found and clarify any misunderstandings.

Homework

Assign a worksheet that requires students to identify and list the common factors for given numbers. The completed homework will be collected and checked without oral presentations from students.
