What Students Need to Do

Students use operations, percentages, rates, equations, tables, and graphs to solve money problems. They interpret results in context and explain how a calculation supports a financial choice.

02

What Mastery Looks Like

Students choose the correct operation or formula and calculate accurately with money, rates, and percentages. They label units, explain their steps, and decide whether an answer is reasonable.
