Livingston County Schools 5th grade Unit 2 Operations and Algebraic Thinking Math Unit Overview Write and interpret numerical expressions. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. Write simple expressions and interpret them. Analyze patterns and relationships. Generate two numerical patterns using two given rules. Identify the relationship between corresponding terms, form ordered pairs and graph them on a coordinate grid.

For example, express the calculation “add 8 and 7, then multiply by 2” as 2 x (8+7). Recognize that 3 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum of product. I can write numerical expressions for given numbers with operation words. X I can write operation words to describe a given numerical expression. X 5.OA.3 Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms for two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and the given rule “Add 6” and the starting number 0, generate the terms in the resulting sequences, and I can generate two numerical patterns using two given rules. X I can form ordered pairs consisting of corresponding terms for the two patterns.
