MA.6.NSO.1.2 · Number Sense and Operations
Students use positive and negative numbers to represent quantities that have opposite directions, such as gaining versus losing money, temperatures above versus below zero, or elevations above versus below sea level. They compare these quantities on a number line and explain what zero means in each situation, for example sea level or a balance of zero dollars.
FAST items for this benchmark are mostly multiple choice questions presenting a real-world situation and asking which integer represents it, what zero means in that context, or which number line model matches the scenario.
