unknown number. 
New York State Next Generation Learning Standards:
3.OA.8

Solve twostep word problems posed with whole numbers and having wholenumber answers using the four operations. Represent these problems using equations or expressions with a letter standing for the unknown quantity.
 Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

expression or equation. 
Ohio's Learning Standards:
3.OA.8

Solve twostep word problems using the four operations.
Represent these problems using equations with a letter or a symbol,
which stands for the unknown quantity. Assess the reasonableness
of answers using mental computation and estimation strategies
including rounding. This standard is limited to problems posed with
whole numbers and having whole number answers. Students may use
parentheses for clarification since algebraic order of operations is
not expected. 
Tennessee Academic Standards:

Solve twostep contextual 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 (See Table 1  Addition and Subtraction Situations and Table 2  Multiplication and Division Situations). 
Wisconsin Academic Standards:
3.OA.D.7

Solve twostep word problems, posed with whole numbers and having whole number answers,
using the four operations. Represent these problems using one or two equations with a letter
standing for the unknown quantity. If one equation is used, grouping symbols (i.e. parentheses) may
be needed. Assess the reasonableness of answers using mental computation and estimation
strategies.
