Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks students to read aloud numbers up to 10,000. Students play a quick “number reading” game where they match numbers in standard form with those written in words. This prepares them to extend to larger numbers.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Definition:
Place value refers to the value of each digit in a number based on its position. In our number system (base-10), each place has ten times the value of the place to its right.
The main place value positions for numbers up to hundred thousand are:
• Ones
• Tens
• Hundreds
• Thousands
• Ten Thousands
• Hundred Thousands
Detailed Explanation with Examples:
Let’s take the number 92,580:
|
Digit |
Position |
Value |
|
9 |
Ten Thousands |
90,000 |
|
2 |
Thousands |
2,000 |
|
5 |
Hundreds |
500 |
|
8 |
Tens |
80 |
|
0 |
Ones |
0 |
More Examples:
1. Example 1:
Number: 54,326
o Digit in hundreds place: 3 → Value = 300
o Expanded form: 50,000 + 4,000 + 300 + 20 + 6
o Word form: Fifty-four thousand three hundred twenty-six
2. Example 2:
Number: 108,743
o Digit in hundred thousands place: 1 → Value = 100,000
o Digit in tens place: 4 → Value = 40
o Expanded form: 100,000 + 0 + 8,000 + 700 + 40 + 3
o Word form: One hundred eight thousand seven hundred forty-three
3. Example 3:
Number: 6,905
o Digit in thousands place: 6 → Value = 6,000
o Expanded form: 6,000 + 900 + 0 + 5
o Word form: Six thousand nine hundred five
Learners’ Activities (Expanded):
1. Activity 1: Place Value Chart Exercise
o Each learner fills out a place value chart for given numbers.
o Example number: 72,419
Hundred Thousands: -
Ten Thousands: 7
Thousands: 2
Hundreds: 4
Tens: 1
Ones: 9
2. Activity 2: Pair Work – Read and Write
o One student reads a number aloud in word form: e.g., "Thirty-five thousand six hundred twelve".
o Partner writes the number in standard form: 35,612
o Then reverse roles.
o They check each other’s work.
3. Activity 3: Build-a-Number Game
o The teacher gives clues, e.g., “A number with 4 in the thousands place, 6 in the hundreds, and 2 in the tens.”
o Learners build the number (e.g., 14,620) and explain each digit’s value.
4. Activity 4: Expanded Form Race
o Learners are given 3 numbers. They must convert all three into expanded form within 5 minutes.
o Example numbers:
83,509 → 80,000 + 3,000 + 500 + 0 + 9
120,004 → 100,000 + 20,000 + 0 + 0 + 0 + 4
7,200 → 7,000 + 200 + 0 + 0
Assessment Checks (Formative):
1. Oral Q&A:
o “What is the value of the digit 6 in 16,829?” → Answer: 6,000
o “Which digit is in the ten thousands place in 58,403?” → Answer: 5
2. Written Questions:
a. Write the number 78,034 in:
o Standard form → 78,034
o Word form → Seventy-eight thousand thirty-four
o Expanded form → 70,000 + 8,000 + 0 + 30 + 4
b. What is the place value of 3 in 43,280?
o 3,000
c. Fill in the blanks:
o 90,000 + ___ + 400 + 10 + 6 = 93,416 → 3,000
3. Classwork Practice:
o Each learner receives a worksheet with 10 numbers. For each:
Identify the value of the underlined digit
Write in expanded and word form
4. Challenge Question:
o The population of a town is 106,025.
What digit is in the thousands place? → 0
Write the number in expanded form.
Is the digit 1 in the hundred thousands or ten thousands place? → Hundred thousands
Extra Practice (Homework Assignment):
• Complete the following for each number below:
a) Identify the value of the digit in the tens place
b) Write in word form
c) Write in expanded form
o 61,428
o 93,507
o 105,210
o 78,003
o 49,675
Key Takeaway Notes:
• Place value determines the value of a digit based on its position.
• Each move to the left in a number increases value tenfold.
• Understanding place value helps us read, write, compare, and perform operations with numbers.
• Standard, word, and expanded forms are different representations of the same number.
• Practice with real-life contexts (like population data, prices, and distances) makes numbers meaningful.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Students summarize how each digit in a number contributes to its overall value. Teacher reinforces that place value is critical for reading, writing, and performing operations with large numbers.
Evaluation Method (Expanded):
Exit slip/quiz: Write the number 86,409 in expanded and word form. State the value of the digit 6.
Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Write three numbers between 70,000 and 100,000 in standard, expanded, and word form.
Follow-up Activity:
At home, ask students to write the population of their community or school enrollment in standard, expanded, and word form.
Differentiation / Inclusive Strategies
Use of number cards and charts to support slower learners. Fast learners create and solve place value riddles for peers.
