1. Name Learning Objective We will compare three-digit numbers using symbols1. CFU What are we going to do? What are symbols? Symbols are __________. Activate Prior Knowledge Place value: The place is the position of a digit in a number. The value is the worth of the digit due to its position. 1. What is the value of the 2 in 271? Make Connection Students, you already know how to find the value of a digit by knowing its position in a number. Now, we will use place value to compare three-digit numbers using symbols. 2. What is the value of the 3 in 321? 1 shapes that stand for something Vocabulary

2. Concept Development To compare numbers means to determine2 whether a number is lessthan, greaterthan, or equaltoanother number. Comparing Numbers < less than 252 < 321 252 has less hundreds than 321. 252 <271 252 has the same hundreds as 271 but less tens. Go to Skill Dev 2 Go to Skill Dev 1 > greater than 321>320 321 has the same hundreds and tens as 320 but more ones. 321 > 252 321 has more hundreds than 252. = equal to 252=252 252 has the same hundreds, tens and ones as 252. CFU 1 Why is the number 367 less than the number 461? A It has less ones. B It has less tens. C It has less hundreds. CFU 2 Why is the number 725 greater thanthe number 721? A It has more ones. B It has more tens. C It has more hundreds. Explain why the number 634 is equal to the number 634. In your own words, what does it mean to compare numbers? To compare numbers _______.
