Common Core State Standards:
Math.4.OA.2 or 4.OA.A.2

Multiply or divide to solve word problems involving multiplicative
comparison, e.g., by using drawings and equations with a symbol
for the unknown number to represent the problem, distinguishing
multiplicative comparison from additive comparison. 
New York State Next Generation Learning Standards:
4.OA.2

Multiply or divide to solve word problems involving
multiplicative comparison, e.g., by using drawings and equations with
a symbol for the unknown number to represent the problem,
distinguishing multiplicative comparison from additive comparison.
See Table 2, page 95. Drawings need not show details, but should
show the mathematics in the problem. (This applies wherever
drawings are mentioned in the Standards.) 
Tennessee Academic Standards:
4.OA.A.2

Multiply or divide to solve contextual problems involving multiplicative comparison, and distinguish multiplicative comparison from additive comparison. For example, school A has 300 students and school B has 600 students: to say that
school B has two times as many students is an example of multiplicative comparison; to say that school B has 300 more students is an example of additive comparison.

Solve word problems involving addition and subtraction of fractions and mixed numbers having like
denominators, using drawings, visual fraction models, and equations to represent the problem. 
Arkansas Academic Standards:
4.NF.B.3.D

Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators (e.g., by using visual fraction models and equations to represent the problem)
Note: Converting a mixed number to an improper fraction should not be viewed as a separate technique to be learned by rote memorization, but simply a case of fraction addition
(e.g., 7 1/5 =7 + 1/5 = 35/5 + 1/5 = 36/5). 
Arizona  K12 Academic Standards:
