CCSS Math Pacing Guide Grade 8 Grade Level: 8th Standard with code: 8.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., For example, by truncating the decimal expansion of show that is between 1 and 2, then between 1.4 and 1.5, and explain how to π2). √2, √2 continue on to get better approximations. Domain: The Number System Cluster: Know that there are numbers that are not rational, and approximate them by rational numbers. Quarter 1: Quarter 2: Quarter 3: Quarter 4: Approximate irrational numbers as rational numbers. Approximately locate irrational numbers on a number line.
