Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. 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.||Common Core Mathematics||Grade 4||Operations And Algebraic Thinking||Use The Four Operations With Whole Numbers To Solve Problems|||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.||Common Core Mathematics||Grade 4||Operations And Algebraic Thinking||Generate And Analyze Patterns|||Mathematical Practices: 1.
