## 5th Grade MULTIPLICATION Standards

### TEKS

**5.1 Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to:**

- B. Use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution.
- C. Select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems.
- D. Communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate.
- E. Create and use representations to organize, record, and communicate mathematical ideas.
- F. Analyze mathematical relationships to connect and communicate mathematical ideas.
- G. Display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication.

**5.4 Algebraic reasoning. The student applies mathematical process standards to develop concepts of expressions and equations. The student is expected to:**

- A. Identify prime and composite numbers; Supporting Standard.
- E. Describe the meaning of parentheses and brackets in a numeric expression; Supporting Standard.

**Common Core**

**Operations & Algebraic Thinking: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.

**Number & Operations - Fractions:Apply and extend previous understandings of multiplication and division.**

- 5.NF.B.5 Interpret multiplication as scaling (resizing), by:
- 5.NF.B.5.A Comparing the size of a product to the size of one factor on the basis of the

size of the other factor, without performing the indicated multiplication.

- 5.NF.B.5.A Comparing the size of a product to the size of one factor on the basis of the
