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

Lesson Plan: Number Sense

Topic

Number Sense

Subject

Mathematics

Grade/Age Group

Grade 1

Length of Lesson

30 minutes

Number of Students

20

Objectives

• Students will be able to identify and understand the concept of numbers and their values.
• Students will practice counting forward and backward within 20.
• Students will recognize and write numbers in both standard and word form.
• Students will develop strategies for simple addition and subtraction using numbers up to 20.

Materials

• Counting manipulatives (e.g., counting bears, blocks, or counters)
• Whiteboard and markers
• Number cards (1-20)
• Worksheets for practice (including number writing and simple equations)
• A timer

National Curriculum Alignment

This lesson aligns with the Common Core State Standards for Mathematics, specifically in Operations and Algebraic Thinking and Number and Operations in Base Ten.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Number Sense	5 minutes	Introduce the concept of numbers. Discuss their importance in everyday life. Ask students to share where they see numbers.
2	Counting Practice	10 minutes	Use manipulatives to practice counting forwards and backwards. Organize a counting session where students count together aloud.
3	Number Recognition Activity	5 minutes	Provide number cards to students. Call out numbers and have students hold up the corresponding number card. Discuss how to write those numbers in word form.
4	Addition and Subtraction Intro	5 minutes	Introduce basic addition and subtraction using visual aids. Show simple equations on the whiteboard and model how to solve them with counting manipulatives.
5	Independent Practice	5 minutes	Distribute worksheets for students to practice writing numbers and solving simple equations on their own.
6	Review and Wrap Up	5 minutes	Go over the answers as a class without individual presentations. Recap key concepts learned about number sense. Remind students to practice at home.

Homework

Complete a worksheet that includes counting, writing numbers, and simple addition/subtraction problems. The homework will be checked by the teacher without students presenting in front of the class.

Assessment

Observe student participation during counting exercises, review completed worksheets, and conduct informal assessments through questions during lesson activities.

Differentiation

• Provide additional support and manipulatives for students who may struggle with counting.
• Offer advanced number challenges for students who quickly grasp foundational concepts.

Conclusion

This lesson aims to create a solid understanding of number sense in students, engaging them with interactive activities while fostering an environment of support and collaboration.
