Kathy stood on the middle rung of a ladder. She climbed up 55 rungs, moved down 44 rungs, and then climbed up 88 rungs. Then she climbed up the remaining 33 rungs to the top of the ladder. How many rungs are there in the whole ladder? Grade 3 TEKS (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; and (G) display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication. The problem above is from Section 1.1 Homework. The 3rd grade TEKS (3.1A, 3.1B, 3.1C, 3.1D, 3.1E, 3.1F, 3.1G) are listed below the problem. 1) What is the answer to the problem above? 2) What TEKS would be assessed with this problem?
