Comparing and ordering numbers up to 1,000,000

Topic Notes

In this lesson, we will learn:

  • To compare whole numbers up to millions place values by finding the biggest place value of difference
  • To order a list of whole numbers up to millions place values by using a place value table

Notes:

  • To compare numbers, look at each place value digit starting on the left (biggest place value)
    • Find the biggest place value where the numbers are different to determine which number is bigger or smaller
    • Ex. 267,043,359 is bigger than 248,143,358
Comparing and Ordering Whole Numbers up to Millions
  • When comparing numbers, we use the symbols:
Comparing and Ordering Whole Numbers up to Millions
    • Ex. 267,043,359 is bigger than 248,143,358
      Therefore, 267,043,359 > 248,143,358

  • There are two ways to order numbers, from:
    • Least to greatest (smallest to biggest)
    • Or greatest to least (biggest to smallest)

  • One tool to help order a list of numbers is by using a place value table
    • Ex. Order the numbers from least to greatest: 12 654, 13 465, 9 546, 11 564
Comparing and Ordering Whole Numbers up to Millions
  • The place value table allows you to compare all place values clearly.
  • 9 546 < 11 564 < 12 654 < 13 465
