Anchor Descriptor - M08.A-N.1.1 Apply concepts of rational and irrational numbers.
-
Eligible Content - M08.A-N.1.1.1 Determine whether a number is rational or irrational. For rational numbers, show that the decimal expansion terminates or repeats (limit repeating decimals to thousandths).
-
Eligible Content - M08.A-N.1.1.2 Convert a terminating or repeating decimal to a rational number (limit repeating decimals to thousandths).
-
Alternate Eligible Content - M08.A-N.1.1.2a Convert a fraction to a decimalup to the hundredths place.
Alternate Eligible Content is designed for students assessed using the PA Alternate System of Assessment (PASA). Essentialized Example resources assist teachers in designing instruction that reduces content complexity while maintaining alignment to academic standards.

-
Eligible Content - M08.A-N.1.1.3 Estimate the value of irrational numbers without a calculator (limit whole number radicand to less than 144). Example: √5 is between 2 and 3 but closer to 2.
-
Eligible Content - M08.A-N.1.1.4 Use rational approximations of irrational numbers to compare and order irrational numbers.
-
Eligible Content - M08.A-N.1.1.5 Locate/identify rational and irrational numbers at their approximate locations on a number line.
-
Alternate Eligible Content - M08.A-N.1.1.5a Locate a non-terminating decimal at its approximate location on thenumber line.
