## Lesson Plan: Place Value (Hundreds, Tens, and Ones)
### Grade Level: 2nd Grade
### Subject: Mathematics
### Duration: 60 minutes
### Topic: Place Value (Hundreds, Tens, and Ones)
#### Objectives:
- Students will understand place value for three-digit numbers.
- Students will be able to identify and write the value of digits in the hundreds, tens, and ones places.
- Students will practice composing and decomposing numbers into hundreds, tens, and ones.
#### Materials:
- Whiteboard and markers
- Place value chart
- Base-ten blocks or manipulatives (hundreds, tens, ones)
- Place value worksheets
- Number cards (0-9)
- Place value song video (optional)
#### Standards:
- CCSS.MATH.CONTENT.2.NBT.A.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.
### LESSON PLAN
#### Introduction (10 minutes):
1. **Greeting and Warm-Up**:
- Start the lesson with a warm-up song. If possible, use a place value song to engage students.
2. **Purpose of the Lesson**:
- Explain to the students that today we are going to learn about place values, focusing on hundreds, tens, and ones.
3. **Review**:
- Briefly review what they already know about tens and ones from previous lessons.
#### Direct Instruction (15 minutes):
1. **Place Value Chart Introduction**:
- Introduce a place value chart on the whiteboard showing hundreds, tens, and ones.
2. **Demonstration with Manipulatives**:
- Use base-ten blocks to explain and visualize the concept. Show a block representing ‘100’, a rod representing ‘10’, and a single cube representing ‘1’.
3. **Example Problem**:
- Write a three-digit number on the board, such as 452.
- Model how to separate the hundreds, tens, and ones:
- 4 hundreds = 400
- 5 tens = 50
- 2 ones = 2
- Show the number in expanded form: 400 + 50 + 2.
#### Guided Practice (15 minutes):
1. **Interactive Activity**:
- Give each student a set of number cards (0-9) and their place value charts.
- Call out a three-digit number and have students create the number using their cards and place it correctly on the place value chart.
- Check and provide feedback.
2. **Group Work**:
- Divide students into small groups and give each group a set of base-ten blocks.
- Give them a three-digit number and ask them to model it using the blocks.
- Rotate among groups to assist and check understanding.
#### Independent Practice (10 minutes):
1. **Worksheets**:
- Distribute place value worksheets where students have to break down three-digit numbers into hundreds, tens, and ones.
- Provide a variety of problems, including writing numbers in expanded form and identifying place values of specific digits.
#### Assessment (5 minutes):
1. **Quick Quiz**:
- Show a number on the board and ask students to write down the value of a specific digit (e.g., "What is the value of the digit 3 in the number 734?").
#### Conclusion (5 minutes):
1. **Recap**:
- Summarize what was learned during the lesson. Emphasize key points about the place value of hundreds, tens, and ones.
2. **Feedback**:
- Ask students to share something new they learned. Address any remaining questions.
3. **Homework**:
- Assign a simple worksheet with practice problems to reinforce the day’s lesson on place value.
#### Clean-Up:
- Allow students to put away any materials or manipulatives they used during the lesson.
### Extensions and Differentiation:
- For advanced students, introduce problems involving rounding to the nearest ten or hundred.
- For students struggling, provide additional practice with smaller numbers and more hands-on activities. Pair them with peers for cooperative learning.
### Note:
- Adapt the lesson to suit the unique needs of your classroom and incorporate technology or additional resources if available.
