  1. Learning Objective We will compare three-digit numbers using symbols1. What are we going to do? What are symbols? Symbols are __________. CFU 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? 200 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. Make Connection 300 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 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 _______. CFU 1 CFU 2 Why is the number 367 lessthanthe number 461? A It has less ones. B It has less tens. C It has less hundreds. < less than 252 < 321 252 has less hundreds than 321. 252 < 321 252 has less hundreds than 321. 252 <271 252 has thesame hundreds as 271 but less tens. 252 < 271 252 has the same hundreds as 271 but less tens. Go to Skill Dev 2 Go to Skill Dev 1 Animated > greater than 321>320 321 has thesame hundreds and tens as 320 but more ones. 321 > 252 321 has more hundreds than 252. 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. 252=252 252 has thesame hundreds, tens and ones as 252. 2 figure out Vocabulary

  3. Skill Development/Guided Practice 1 To compare numbers means to determine whether a number is lessthan, greaterthan, or equaltoanother number. How did I/you compare each digit in the numbers? How did I/you know which symbol to write? CFU Compare three-digit numbers using symbols. 1 Compare each digit in the numbers, starting at the highest place value. If digits are different, identify3 the smaller digit. (underline) If digits are the same, continue to the next lower place value. Write the correct symbol. Interpret4 your answer. 1 2 a b 2 3 < less than 3hundreds. > greater than 379 has lesshundreds than 456 168 has lesshundreds than 231 2tens. = equal to 7ones. 3 find 4 explain Vocabulary 142 has the samehundreds and tens as 145, but lessones 248 has the samehundreds as 267, but lesstens

How did I/you compare each digit in the numbers? How did I/you know which symbol to write? CFU Compare three-digit numbers using symbols. 1 Compare each digit in the numbers, starting at the highest place value. If digits are different, identify the smaller digit. (underline) If digits are the same, continue to the next lower place value. Write the correct symbol. Interpret your answer. 1 2 a b 2 Back to Concept Dev 3 < less than > greater than 480 has lesshundreds than 554 678 has lesshundreds than 804 = equal to 422 has the samehundreds as 435, but lesstens 340 has the samehundreds and tens as 349, but lessones

  5. Skill Development/Guided Practice 2 To compare numbers means to determine whether a number is lessthan, greaterthan, or equaltoanother number. How did I/you compare each digit in the numbers? How did I/you know which symbol to write? CFU Compare three-digit numbers using symbols. 1 Compare each digit in the numbers, starting at the highest place value. If digits are different, identify the smaller digit. (underline) If digits are the same, continue to the next lower place value. Write the correct symbol. Interpret your answer. 1 2 a b 2 3 < less than 3hundreds. > greater than 251 has more hundreds than 123 235 has more hundreds than 184 2tens. = equal to 7ones. 179 has the samehundreds and tens as 173, but more ones 237 has the samehundreds as 227, but more tens

How did I/you compare each digit in the numbers? How did I/you know which symbol to write? CFU Compare three-digit numbers using symbols. 1 Compare each digit in the numbers, starting at the highest place value. If digits are different, identify the smaller digit. (underline) If digits are the same, continue to the next lower place value. Write the correct symbol. Interpret your answer. 1 2 a b 2 3 < less than 126 has the sameones, tens, and hundreds as 126 173 has the sameones, tens, and hundreds as 173 > greater than = equal to 395 has the samehundreds and tens as 393, but more ones 774 has morehundreds than 623

  7. Relevance To compare numbers means to determine whether a number is lessthan, greaterthan, or equaltoanother number. Comparing numbers will help you know which amount is more or less. 1 Which group of books would you rather carry? 120 pounds 9pounds or Comparing numbers will help you do well on tests. 2 Does anyone else have another reason why it is relevant to compare numbers using symbols? (Pair-Share) Why is it relevant to compare numbers using symbols? You may give me one of my reasons or one of your own. Which reason is more relevant to you? Why? CFU Sample Test Question: 42.
