Course 1 Chapter 1 Section1 Understanding Whole Numbers
Reviewing Skills You Need: Place Value
Write the value of the digit 2 in each number: 28: 20 2 8,672: 612,980: 2,000 7,249,800,401: 200,000,000
Objective 1: Writing and Comparing Whole Numbers Standard Form: Uses Digits and Place Value to express numbers Uses commas to separate values Example: 2,623,684,608,000 Expanded Form: A sum that shows the place and value of each digit in the number Example: 6000 + 500 + 40 + 2
Example 1: Writing a Whole Number in Words 2,623,684,608,000 2,000,000,000,000 + 623,000,000,000 + 684,000,000 + 608,000 2 Trillion 623 Billion 684 Million 608 Thousand Two Trillion, six hundred twenty-three billion, six hundred eighty-four million, six hundred eight thousand
Example 2: Comparing and Ordering Whole Numbers Use < or > to complete 995 998 995 998 995 is on the left of 998 on the number line above So, 995 < 998
Example 2: Comparing and Ordering Whole Numbers Write in order from least to greatest: 9,797; 9,987; 9,789 The first digit is the same Compare the tens digit in the remaining numbers. 9 is greater than 8, so 9,797 is the next largest number 9,797 9,987 9,789 9 is the largest digit so 9,987 is the largest number The order from least to greatest is: 9,789; 9,797; 9,987
