**Lesson Plan: Counting and Place Value**
**Grade:** 1
**Duration:** 60 minutes
**Subject:** Mathematics
**Topic:** Counting and Place Value
**Objective:**
By the end of the lesson, students will be able to:
1. Count from 1 to 100.
2. Understand the concept of place value (ones, tens, hundreds).
3. Represent two-digit numbers using place value.
**Materials Needed:**
- Whiteboard and markers
- Number cards
- Base-10 blocks (units, rods)
- Counting charts (1–100)
- Place value mats
- Worksheets for practice
- Crayons or colored pencils
**Common Core Standards:**
- CCSS.MATH.CONTENT.1.NBT.A.1: Count to 120, starting at any number less than 120.
- CCSS.MATH.CONTENT.1.NBT.B.2: Understand that the two digits of a two-digit number represent amounts of tens and ones.
**Lesson Introduction (10 minutes):**
1. **Greeting and Warm-Up:**
- Greet the students and briefly review numbers 1–20.
- Sing a counting song or rhyme to get students engaged.
2. **Introduction to Lesson:**
- Explain the lesson objective: We are going to learn how to count up to 100 and understand place value.
**Direct Instruction (15 minutes):**
1. **Counting to 100:**
- Use the counting chart to count aloud with the class from 1 to 100.
- Pause at intervals (e.g., every 10th number) to emphasize patterns in counting.
2. **Understanding Place Value:**
- Show students base-10 blocks and explain the units (ones) and rods (tens).
- Demonstrate how ten ones make a ten rod.
- Introduce place value using a place value mat. Write a two-digit number and break it into tens and ones.
**Guided Practice (15 minutes):**
1. **Place Value Activities:**
- Hand out place value mats and number cards to each student or small group.
- Call out numbers, and have students place the correct number of tens and ones on their mats using base-10 blocks.
- Encourage students to share their responses with the class.
2. **Interactive Game:**
- Play a game where students draw number cards and represent the numbers using base-10 blocks on their place value mats.
**Independent Practice (10 minutes):**
1. **Worksheet Completion:**
- Distribute worksheets that focus on counting and place value.
- Provide different sections like counting to 100, writing numbers in tens and ones, and matching numbers to the correct base-10 representation.
- Circulate the room to assist and encourage students as they work.
**Review and Closing (10 minutes):**
1. **Display Student Work:**
- Have students share what they learned or display their worksheets.
- Discuss any common mistakes and correct them as a class.
2. **Closing Activity:**
- End with a quick number game or a counting song to reinforce learning.
- Summarize the main points of the lesson.
**Assessment:**
- Observe students during guided and independent practice.
- Review completed worksheets to ensure understanding of counting and place value concepts.
- Use informal questioning to gauge comprehension throughout the lesson.
**Differentiation:**
- Provide additional support for students who need it with smaller number ranges or one-on-one help.
- Challenge advanced students with numbers beyond 100 or introduce the concept of hundreds place.
**Homework:**
- Assign a worksheet with additional counting and place value problems to reinforce the day’s lesson at home.
**Reflection:**
- Reflect on the lesson's effectiveness. Note which activities were successful and which might need adjustment for future lessons.
