Lesson Plan: Comparing Numbers to 20

Subject: Mathematics Grade Level: Primary 1 (6-7 years old)

Introduction: - Begin the lesson by displaying a number line from 1 to 20 on the board or using a physical number line in the classroom. - Engage the students by asking them to identify the numbers on the number line and discuss their understanding of numbers up to 20. - Explain that today, they will be learning how to compare numbers to 20 and understand the concepts of greater than, less than, and equal to.

Lesson Outline:

- Review:
- Review numbers from 1 to 20 with the students, ensuring they can identify and count them accurately.
- Use flashcards or number charts to reinforce their understanding.

- Introduction to Comparing Numbers:
- Explain the concept of comparing numbers by using examples of everyday objects, such as fruits or toys.
- Show two different quantities of objects and ask the students to identify which group has more, less, or if they are equal.
- Introduce the symbols for greater than (>), less than (<), and equal to (=).

- Comparing Numbers to 20:
- Use visual aids, such as number cards or manipulatives, to compare numbers up to 20.
- Start with simple comparisons, such as 5 and 10, and gradually increase the difficulty.
- Model how to compare numbers using the symbols (>,

Questioning: - During the lesson, ask the following questions to assess students’ understanding: 1. Which number is greater: 12 or 15? 2. Which number is less: 8 or 4? 3. Are 10 and 10 equal? 4. Can you compare 20 and 5 using the symbols?

Assessment: - Distribute a worksheet with a variety of number comparison problems. - Observe students as they complete the worksheet to assess their understanding. - Provide individual support and guidance as needed.

Differentiation: - For students who need additional support, provide manipulatives or number lines to help them visualize and compare numbers. - For students who grasp the concept quickly, challenge them with more complex number comparisons or ask them to explain their reasoning.

Plenary: - Summarize the lesson by reviewing the concepts of comparing numbers to 20. - Ask students to share their understanding of greater than, less than, and equal to. - Use a video resource to reinforce the concepts learned, such as: - “Comparing Numbers Song” by Have Fun Teaching: https://www.youtube.com/watch?v=0VLxWIHRD4E - “Comparing Numbers to 20” by Math & Learning Videos 4 Kids: https://www.youtube.com/watch?v=3X0z8z3XgZU
