4.NBT.A.1 CCSS.MATH

Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.

4.NBT.A.2 CCSS.MATH

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form, and compare them.

4.NBT.A.3 CCSS.MATH

Use place value understanding to round multi-digit whole numbers to any place.

📦 Materials Needed

Place value chart
Digit cards
Whiteboard
Number comparison cards

🎯 Teaching Strategies

💡

Use a Place Value Chart Keep a visible chart so students can place digits into thousands, ten-thousands, and hundred-thousands before reading or comparing.

💡

Compare Left to Right Model comparison as a step-by-step scan from the greatest place instead of a guess based on the last digits.

💡

Link Rounding to Benchmarks Have students identify the two benchmark numbers a value sits between before deciding which one is closer.

⚠️ Common Misconceptions

❌ Misconception: A larger last digit always means the whole number is greater

✅ Correction: Show counterexamples where the greatest place value matters more than the last digit.

❌ Misconception: Students round using the target digit instead of the digit to its right

✅ Correction: Use arrows or boxes to mark the target place and the deciding digit.

📊 Differentiation Tips

Struggling

Stay with five-digit numbers and expanded form until the place-value pattern feels secure.

On-level

Mix reading, writing, comparing, and rounding in the same practice set.

Advanced

Ask students to explain why one digit is ten times the value of another in the same number.

🚀 Extension Activities

Build large numbers with digit cards and read them aloud.
Create a comparison game using four six-digit numbers.
Round real-world numbers from sports, travel, or population examples.
