## 2nd Grade FRACTIONS Standards

### TEKS

**2.1 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.

**2.3 Number and operations. The student applies mathematical process standards to recognize and represent fractional units and communicates how they are used to name parts of a whole. The student is expected to:**

- A. Partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words.
- B. Explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part.
- C. Use concrete models to count fractional parts beyond one whole using words and recognize how many parts it takes to equal one whole.
- D. Identify examples and non-examples of halves, fourths, and eighths.
