Ordering Real Numbers

Warm Up Order the numbers from least to greatest. 7 , 2, 8 2 220 , −10, 100 , 11.5 10 , 𝜋, 3.5 8 , −3.75, 3, 9 4

Order a set of real numbers. Use rational approximations to compare the sizes of irrational numbers. Order numbers for real-world situations. Compare irrational numbers. Estimate the value of expressions with irrational numbers. Understand the relative sizes of numbers in different forms in the real number system.

To order a set of real numbers, find their approximate decimal values and order them.

To order two numbers in different forms whose decimal approximations appear to be equal, approximate one or both numbers to an additional number of decimal places.

Give an example of each type of number.

Jill says that 12. 6 is less than 12.63. Explain her error.
