Standards and Resources

Common Core Standards:

• MCC8.NS.1: Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
• MCC8.NS.2: Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions(e.g., π 2). For example, by truncating the decimal expansion of √2 (square root of 2),show that √2 is between 1 and 2,then between 1.4 and 1.5, and explain howto continue on to get better approximations.
• MCC8.EE.2: Use square root and cube root symbols to represent solutions to equations of the form x^2= p and x^3 =p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
