- 4.NBT.2: Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place.
- 4.NBT.1: 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.OA.3: Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations.
- Place Value Understanding: Recognizing value of each digit position
- Number Sense: Developing intuition for number magnitude
- Logical Reasoning: Applying systematic comparison methods
- Pattern Recognition: Identifying relationships between numbers
- Symbol Usage: Correct application of >, <, and = symbols
- Problem Solving: Using strategies to solve comparison problems
- Count digits: More digits usually means larger number
- Compare from left to right: Start with highest place value
- Identify first difference: Find where digits differ
- Determine relationship: Compare the differing digits
- Select symbol: Use >, <, or = appropriately
- Verify: Double-check your answer
• Both have 5 digits
• Compare from left: 4=4, 5=5
• First difference: 6 vs 7 in hundreds place
• Since 6 < 7, then 45,678 < 45,721
• All have same first 3 digits (234)
• Compare hundreds place: 5, 6, 5
• Among 5s: compare tens place 67 vs 76
• Answer: 234,567 < 234,576 < 234,657
• Place Value Understanding: Recognizing the value of each digit position
• Number Sense: Developing intuition for number magnitude

• Beginner: 2-3 digit numbers with clear differences
• Intermediate: 4-5 digit numbers requiring careful comparison
• Advanced: 6+ digit numbers with multiple similarities
• Expert: Mixed formats and word problems
Place Value: The value of a digit based on its position in the number
Comparison: Determining if one number is greater than, less than, or equal to another
Ordering: Arranging numbers in ascending or descending sequence
Super Numbers: Numbers with 4 or more digits (thousands, ten thousands, etc.)
- Count digits: More digits usually means larger number
- Compare from left to right: Start with highest place value
- Identify first difference: Find where digits differ
- Determine relationship: Compare the differing digits
- Select symbol: Use >, <, or = appropriately
- Verify: Double-check your answer
• Start Left: Always compare from the highest place value
• More Digits: Generally means larger number (positive numbers)
• First Difference: Determines the relationship
• Symbol Use: > for greater, < for less, = for equal
• Zero Impact: Internal zeros affect value significantly
• Standard Form: Understand expanded and standard forms
