### Lesson Plan: Understanding and Comparing Numbers
**Grade:** 1st Grade
**Subject:** Mathematics
**Duration:** 45-60 minutes
**Topic:** Understanding and Comparing Numbers
---
**Objective:**
By the end of the lesson, students will be able to:
1. Understand the concept of numbers up to 20.
2. Compare numbers using terms like "greater than", "less than", and "equal to".
3. Use symbols (>, <, =) to compare numbers.
### Materials:
- Number cards (1-20)
- Greater than, less than, and equal to visual aids (e.g., alligator mouth symbols)
- Whiteboard and markers
- Worksheets with number comparison exercises
- Counter objects (e.g., small toys, beans, or blocks)
- Visual number line (0-20)
- Interactive whiteboard or Laptop (optional for digital activities)
### Introduction (10 minutes):
1. **Welcome and Warm-up Activity:**
- Greet the students and have a quick number song or chant to get them excited about the activity (e.g., "One, two, buckle my shoe...").
2. **Set the Scene:**
- Explain the day's objective: "Today, we are going to learn how to compare numbers and figure out which ones are bigger or smaller."
3. **Review Counting:**
- Briefly review counting from 1 to 20 to ensure everyone is comfortable with the range of numbers.
### Direct Instruction (15 minutes):
1. **Explaining Terms:**
- Introduce the terms "greater than", "less than", and "equal to". Use examples:
- "5 is less than 7"
- "8 is greater than 3"
- "10 equals 10"
2. **Using Visuals:**
- Display and explain number lines and how they can help to understand which number is greater or smaller.
- Use visual aids like the alligator mouth symbols, explaining that the alligator always wants to eat the bigger number (e.g., 7 > 4).
3. **Demonstrations:**
- Show several examples on the board using large number cards and greater than/less than/equal to symbols.
- Have students suggest comparisons and participate in the decision-making process.
### Guided Practice (15 minutes):
1. **Pair Work:**
- Divide students into pairs and provide them with number cards and comparison symbols.
- Ask them to draw two number cards and decide which symbol fits best between the numbers.
2. **Interactive Game:**
- Arrange a "Number Battle" game where pairs of students draw cards and quickly decide which card is greater. The student with the larger number keeps both cards. Continue playing until time runs out.
### Independent Practice (10 minutes):
1. **Worksheet Activity:**
- Pass out worksheets with pre-printed number pairs and spaces to fill in the correct symbols (>, <, =).
- Circulate and offer support as needed, ensuring understanding and correct application of the symbols.
### Closure (5 minutes):
1. **Review:**
- Gather the students and review a few examples from the worksheet or student pairs’ comparisons.
- Reinforce the day’s learning objectives and praise the students for their participation and understanding.
2. **Exit Ticket:**
- Have each student draw a number from a jar and say a number that is greater than or less than the one they picked as their "exit ticket".
### Assessment:
- Observational assessment during the guided practice and interactive game.
- Worksheet accuracy.
- Exit ticket responses.
### Differentiation:
- For advanced students, introduce numbers up to 50 or integrate simple addition/subtraction comparison problems.
- For students needing more support, use manipulatives like counters or a visual number line to help them visualize the comparisons.
### Homework/Extension:
- Send home a simple worksheet or suggest an online interactive game focusing on number comparison.

### Reflective Notes for Next Lesson:
- Consider student engagement and understanding during interactive activities.
- Adjust pacing based on students' grasp of concepts.
- Plan to revisit any concept that seemed challenging for a significant number of students.
