NC.8.NS.1 Understand that every number has a decimal expansion. Building upon the definition of a rational number, know that an irrational number is defined as a non-repeating, non-terminating decimal.
NC.8.NS.2 Use rational approximations of irrational numbers to compare the size of irrational numbers and locate them approximately on a number line.
Estimate the value of expressions involving:
Square roots and cube roots to the tenths.
𝜋 to the hundredths.
NC.7.NS.3 Solve real-world and mathematical problems involving numbers using the four operations.
