Outcomes

7.NS.A.3

Solve real-world and mathematical problems involving the four operations with rational numbers. (Note: computations with rational numbers extend the rules for manipulating fractions to complex fractions.)

7.EE.B.3

Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.
