Place Value Study Guide Name: ____________________________________________________ Test: _____________________ _____ Can you tell the expanded form, word form, and standard form of a number that goes through the millions place? Example: 4,590,457 (this is standard form) Expanded form: 4,000,000 + 500,000 + 90,000 + 400 + 50 + 7 Word form: four million, five hundred ninety thousand, four hundred fifty-seven _____ Do you know the names of the places and their values? (You need to be able to apply this information.) Millions, 1,000,000 Hundred thousands 100,000 Ten thousands 10,000 Thousands, Hundreds Tens Ones 1,000 10 1 100 _____ Do you know the difference between an odd number (1, 3, 5, 7, 9) and an even number (0, 2, 4, 6, 8)? _____ Can you compare numbers using place value words? Example: Mrs. Daniels changed the 3 in the number 23,412 to a 6. How does that change the value? Answer: The value is increased by 3,000 because the 3 is in the thousands places. Changing the 3 to a 6 means that I am adding 3 more thousands. Strategy: Re-write the number with the new digit in it and compare numbers. 23,412 becomes 26,412. It may be easier to see that you have added 3,000 to the number. Or, you could subtract 26,412 – 23,412 to arrive at the same answer. _____ Can you compare numbers? 235,102 > 234,102 2,058,385 < 2,058,435
