GRADE 4 Operations and Algebraic Thinking (OA)
Use the four operations with whole numbers to solve problems
4.OA.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 ? 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

GRADE 4 Operations and Algebraic Thinking (OA)
Generate and analyze patterns
4.OA.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.
A student should know
? A pattern is a set of numbers or objects which relate to each other according to a specific rule.
