Compare and Order Numbers to at least 1,000,000 3 - Reasoning

In an exercise designed to develop reasoning skills in number and place value, students are presented with a challenge to compare and order numbers up to at least 1,000,000. Three children, Malachi, Leanna, and Rosie, each have a number, and the task is to determine who has which number based on the clues provided. Malachi's number is 263,603; Leanna's number is 294,503; and Rosie's number is 275,503. The clues given are as follows: one child's number is smaller than 290,000; another's number is greater than Malachi's number; and the last clue reveals that a child's number is exactly 10,000 more than 284,503.

By analyzing the clues, students can deduce the correct assignment of numbers to each child. The first clue indicates that one of the numbers is smaller than 290,000, which applies to Malachi's number. The second clue states that one child's number is greater than Malachi's number, which could apply to either Leanna or Rosie. Finally, the third clue identifies a number that is exactly 10,000 more than 284,503, which calculates to 294,503, and this must be Leanna's number. Therefore, the remaining number, 275,503, is Rosie's, as it is greater than Malachi's but less than Leanna's. This exercise helps students practice logical deduction and understand the significance of place value in comparing and ordering large numbers.
