1. Place Value up to Millions
Cambridge Primary Mathematics -
Grade 4

2. Warm-Up
• 📝 Quick Question:
• - What is the value of 5 in 5,000?
• - Is it the same as in 50?
• 👉 Let students discuss before showing the
answer.

3. Introduction: What is Place Value?
• - A digit’s value depends on its position in the
number.
• - Example: In 3,456 → '3' is in the Thousands
place.
• Difference:
• - Value = the number itself (e.g., 5 = five).
• - Place Value = its value based on position
(e.g., 5 in 5,000 = five thousand).

4. Place Value Chart (Ones to
Thousands)
• Thousands | Hundreds | Tens | Ones
• Example: 3,456
• - 3 → Thousands → 3,000
• - 4 → Hundreds → 400
• - 5 → Tens → 50
• - 6 → Ones → 6

5. Place Value Chart (Up to Millions)
• Millions | Hundred Thousands | Ten
Thousands | Thousands | Hundreds | Tens |
Ones
• Example: 2,345,678
• - 2 → Millions → 2,000,000
• - 3 → Hundred Thousands → 300,000
• - 4 → Ten Thousands → 40,000
• - 5 → Thousands → 5,000

6. Guided Practice
• Example: What is the value of 7 in 7,324,581?
• 👉 Answer: 7,000,000 (Seven million)
• Activity:
• - Ask students: What is the place value of 2?
• - Encourage peer discussion.

7. Student Activities
• - Build numbers using digit cards.
• - 'Guess My Number' Game: One student
chooses a number, others ask yes/no
questions.
• - Pair Work: Identify each digit’s value in
4,508,209.

8. Thinking and Working
Mathematically
• - TWM.07 (Critiquing): Students explain and
critique each other’s reasoning.
• - TWM.08 (Improving): Compare different
methods to understand numbers.
• 👉 Encourages reasoning, communication,
and collaboration.
