Lesson Plan: Place Value Using 100 Chart

Subject: Mathematics

Grade: 1

Duration: 30 minutes

---

Objectives

By the end of this lesson, students will be able to:

• Understand the concept of place value.
• Identify numbers on a 100 chart.
• Recognize the importance of tens and ones in numbers.

---

Materials Needed

• 100 charts (1 per student)
• Markers or crayons
• Whiteboard and dry erase markers
• Printed handouts of numbers 1-100 for reference
• Place value blocks (optional)

---

Introduction (5 minutes)

Begin the lesson by asking students if they know what place value means. Briefly explain that place value shows the value of each digit in a number, based on its position.

Present the 100 chart, showing how it helps us visualize numbers up to 100. Explain that in a two-digit number, the first digit represents the “tens” place and the second digit represents the “ones” place.

---

Direct Instruction (10 minutes)

1. Demonstration on the 100 Chart
   Use the whiteboard to draw a simple 100 chart. Point out the rows and columns and explain how the numbers increase across the row and down the column.

2. Identifying Place Value
   Demonstrate how to find numbers on the chart:

   • If you find the number 27, explain that there are 2 tens (20) and 7 ones (7).
   • Repeat with a few more examples: 34 (3 tens and 4 ones), 58 (5 tens and 8 ones).

3. Using Place Value Blocks (Optional)
   Show place value blocks to visually represent tens and ones. For instance, show 2 blocks for tens and 7 blocks for ones to represent the number 27.

---

Guided Practice (10 minutes)

1. Finding Numbers on the Chart
   Hand out the 100 charts to the students.
   Ask them to find specific numbers, such as:

   • "Find the number 45 on your chart."
     Discuss how the number is made up of 4 tens and 5 ones.

2. Interactive Group Activity
   Organize students into pairs and give them different numbers to find on their charts.
   Encourage them to explain to their partners the place value of each number they find.

---

Independent Practice (5 minutes)

Distribute handouts with a few numbers written on them.
Students will identify the tens and ones for each number listed. For example:

• Number: 62 → Tens: 6, Ones: 2
• Number: 18 → Tens: 1, Ones: 8

As students work, circulate the room to provide support and answer questions.

---

Closure (5 minutes)

Bring the class back together and ask a few students to share their answers for the independent practice.
Reinforce the idea of place value by highlighting how understanding tens and ones helps us with larger numbers.

End with a fun fact: "When we understand place value, we can even add and subtract bigger numbers later!"

Assessment

• Observations during guided practice.
• Review answers from the independent practice handouts.

---

Extensions

For students who finish early or need additional challenges:

• Create two-digit numbers with a partner and ask them to show the values using the 100 chart and place value blocks.
• Encourage students to come up with their own numbers and write them down, identifying the tens and ones.
