Domain:
Operations and Algebraic Thinking
Cluster:
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
Standard:
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Footnote:
This standard is limited to problems posed with whole numbers and having whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
