Comparing whole numbers In Grade 4 you learnt what it means to compare numbers, how to compare numbers, and which symbols to use to compare numbers. When you compare numbers, you must look at the value of the digits Compare the following numbers and circle the greatest number:
4 953 4 593 4 539
You already know how to compare numbers because you can order numbers. You also compare numbers when you complete sequences on number charts or number lines Example: Which whole numbers do the letters A and B represent?
25
A
29
31
B
Answer: A = 27 AND B = 33 You can now compare numbers, say which number is the greatest and which is the smallest, and arrange them. But how do you indicate which number is the greatest or smallest without circling or underlining it?
