1. Order of Operations A Unit Plan by Erica Kohr

2. Critical Questions What are expressions? How do you use parentheses in a math sentence? How do you evaluate expressions using order of operations? How do you write expressions?

3. Standards CCSS.Math.Content.5.OA.A.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. CCSS.Math.Content.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.

4. Unit Summary Significance: The unit will teach students how to interpret and evaluate mathematical expressions Skills needed/Prior Knowledge: basic addition, multiplication, subtraction, and division. the order of operations and how to read mathematical sentences. be able to put their work into their words

5. Unit Summary Skills Attained: How to evaluate expressions Putting expressions into words How to read expressions with multiple operations Instructional Methods: Group work Partner activities Worksheets Modeling Stations

6. Academic Language Order of Operations Parentheses Exponents Multiplication Division Subtraction Addition Expressions Evaluate
