  1. Name Learning Objective We will write numbers using expanded form. CFU What are we going to learn? 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. Find the place value for the following digits of 258. 1.2 is in the __________ place. The value of the 2 in 258 is _________. 2.5 is in the __________ place. The value of the 5 in 258 is _________. Make Connection Students, you already know how to identify the place value of digits in a number. Now, we will use place value to write numbers in expanded form.

  2. Concept Development Expanded1 formrepresents2 a number as the addition of the value of each digit. • The expanded form of a number is equal to the original3 number. Expanded Form Original Number Expanded Form 258 = 200+50+8 The value of the2in 258 is 2 0 0 The value of the 5 in 258 is 50 The value of the 8 in 258 is 8 + 2 5 8 NOT Expanded Form Vocabulary 1 made longer (gesture) 2 shows (synonym) 3 beginning 258 is NOT2 + 5 + 8 CFU 1 Which number is equal to 700 + 60 + 4? How do you know? A 764 B 704 C 746 Why is 7 + 6 + 4 not the expanded form of 764

  3. Skill Development/Guided Practice Expanded form represents a number as the addition of the value of each digit. • The expanded form of a number is equal to the original number. Use expanded form to represent numbers. Read the number aloud. Identify4 the digit in the ones place. (write “o”) Identify the digit in the tens place. (write “t”) Identify the digit in the hundreds place. (write “h”) Write the number as the addition of the value of each digit. Hint: Start at the highest value. 1 a b c 2 3 7 6 5 1 4 The expanded form of 376 is _____________________. The expanded form of 514 is _____________________. 2 0 6 5 0 8 The expanded form of 206 is _____________________. The expanded form of 508 is _____________________. 6 3 0 7 4 0 The expanded form of 630 is _____________________. The expanded form of 740 is _____________________. CFU How did I/you identify the digit in each place value? How did I/you write the expanded form of the number? 4 find (synonym) Vocabulary 1a-c 2

  4. Relevance Expanded form represents a number as the addition of the value of each digit. • The expanded form of a number is equal to the original number. Writing numbers using expanded form will help you better understand what numbers mean. 1 My uncle George won the lottery. He won five thousand, nine hundred twenty-seven dollars. 5,000 + 900 + 20 + 7 = $5,927 2 Writing numbers using expanded form will help you do well on tests. Sample Test Question: 10. Sophie has 527 seashells in her collection. Which of these equals 527? A 5 + 2 + 7 B 5 + 20 + 700 C 500 + 20 + 7 D 500 + 200 + 70 Sample Test Question: 11. Which number is 400+ 80 + 5? A 458 B 485 C 4085 D 405 Does anyone else have another reason why it is relevant to write numbers using expanded form? (Pair-Share) Why is writing numbers using expanded form relevant? You may give me one of my reasons or one of your own. Which reason is more relevant to you? Why? CFU
