Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 4. dentify 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. This standard has to do with reasoning about number and shape patterns that follow a given rule. Grade appropriate shape patterns might include a repeated sequence of shapes or a growing shape pattern.
