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: 1:1 Correspondence

Subject

Mathematics

Topic

1:1 Correspondence

Grade/Age Group

Preschool / Nursery (Ages 3-5)

• Small counters (e.g., bears, blocks, or buttons)
• Worksheets with images of objects (e.g., apples, stars)
• Large chart paper for group activity
• Markers
• Music for transition (optional)

National Curriculum Standards

This lesson aligns with the following Early Childhood Mathematics Standards:

• Recognizing and applying concepts of one-to-one correspondence.
• Counting objects in a set and understanding quantity.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 min	Briefly explain the concept of 1:1 correspondence. Use visual aids to demonstrate.
2	Group Activity	10 min	Divide students into pairs. Provide each pair with counters, guiding them to match items one-to-one.
3	Individual Practice	5 min	Hand out worksheets with images for students to count and circle the items in pairs.
4	Guided Discussion	5 min	Gather students and discuss their findings from the worksheet. Ask open-ended questions about their matching.
5	Review and Transition	5 min	Summarize what they learned about 1:1 correspondence. Transition to a closing activity with music.

Homework

• Students will take home a counting worksheet that requires them to find and draw pairs of objects from their home environment.
• The homework will be checked in subsequent classes without requiring presentations from students.

Assessment

• Observe students during group and individual activities to assess their understanding of 1:1 correspondence.
• Review the completed worksheets for accuracy and understanding.
