7.EE.B.3: Multi-step number problems

Also written as 7.EE.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.

In plain words: Students solve multi-step real-life and mathematical problems with positive and negative whole numbers, fractions, and decimals, switch forms when it helps, and check answers by estimating.

Common mistake
Adding percents that apply one after the other: a 20% discount and then 10% tax is 0.8 × 1.1 = 0.88 of the price, not 10% off.
