Grade 4 GT Mathematics
Operations & Algebraic Thinking (5.OA)
During this unit of study, students learn to use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. They will learn to write simple expressions that record calculations with numbers, and interpret numerical expressions. Additionally, students will analyze patterns and relationships by generating two numerical patterns using two given rules. They will identify apparent relationships between corresponding terms and form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane.

What will my child learn?
Students will:
Write and interpret numerical expressions.
5.OA.A.1
Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
5.OA.A.2
Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2(8 + 7). Recognize that 3(18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
Analyze patterns and relationships.
5.OA.B.3
Generate and analyze patterns and relationships. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.
