Operations and Algebraic Thinking MCC5.OA.1, MCC5.OA.2, MCC5.OA.3

Standards MCC5.OA.1 - Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. MCC5.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 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product. MCC5.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.

Directions Split class into 5 teams (or less). Each team must solve the given problem. After time is called, every team leader should hold their answer so it can be checked. Teacher is to click on the yellow square for answer to appear. The teams that got the correct answer choose a bubble. Teacher is to click on the bubble to reveal points earned. Tip: Alternate which team chooses bubble first
