Order of operations worksheet: evaluate 2 × [15 − (3 + 4)], place parentheses so 6 + 4 × 5 = 50, translate word phrases, and compare 4 × (1,280 + 345).
5.OA expressions: using parentheses, brackets, or braces in numerical expressions and evaluating expressions containing these symbols.

Order of operations worksheet: evaluate 2 × [15 − (3 + 4)], place parentheses so 6 + 4 × 5 = 50, translate word phrases, and compare 4 × (1,280 + 345).

Evaluate expressions with parentheses and brackets for 5.OA.1: step through 3 × [14 - (2 + 7)], place symbols so 30 - 2 × 5 + 3 = 14, share granola bars.

Bingo game for order of operations: 16 bracketed expressions from 4 + (6 × 3) to 100 − [5 × 12], each answer crossed off a 4 × 4 MATH board (5.OA.1).

Numerical patterns worksheet: build add-2 and add-4 sequences from 0, graph (2, 4) through (8, 16), explain y = 2x, then crack Maya's hidden rules (5.OA.3).

Fill-in worksheet for numerical expressions: complete (9 + __) × 3, write 40 ÷ (3 + 5) from words, and see why 4 × (1,250 + 380) is 4 times the sum.

Order of operations story problems: write expressions for card packs and savings jars, cost robotics kits to $92, and count change from $100 at the pool.
5.OA.1
“Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.”
5.OA.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 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.”
5.OA.3
“Generate two numerical patterns using two given rules. 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, and given the rule "Add 6" 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.”
