## 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:**

A. Apply mathematics to problems arising in everyday life, society, and the workplace;

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.

Measurement & Data

Reason with shapes and their attributes.

3.G.A.2 Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.

*For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape*.
