Compare and Order Numbers to at least 1,000,000 5 - Reasoning

In a reasoning task involving number and place value, students are challenged to compare and order a set of numbers reaching into the millions. The task requires a clear understanding of the value of each digit according to its position, in order to accurately determine the sequence from the greatest to the smallest number. The numbers in question are 274,553; 274,535; 274,355; 247,553; and 247,535. The exercise asks which number would come third if these were arranged starting with the greatest.

Upon examining Rosie's answer, it is revealed that she is incorrect. The correct order, starting with the greatest, is 274,553 followed by 274,535, and then 274,355. Therefore, the third number in the sequence is 274,355, not 274,553 as Rosie had stated. When ordering these numbers, it is crucial to compare the digits from left to right, starting with the highest place value, which in this case is the hundreds of thousands place. By following this method, students can accurately determine the sequence of numbers, enhancing their understanding of number and place value concepts.
