Evaluation for 5.5a
TEKS process standards are integrated appropriately into the materials.
The materials integrate the TEKS process standards. Materials include opportunities for students to use a problem-solving model that incorporates analyzing given information (identifying what is known), formulating a plan (choosing appropriate strategies), determining a solution, and justifying the solution. The materials provide opportunities for students to communicate mathematical ideas using multiple representations, including symbols, diagrams, arrays, and mathematical language when explaining their reasoning. Students have opportunities to select appropriate tools, such as manipulatives (counters, base-ten blocks), visual models (arrays, area models), and techniques (mental math, estimation) to solve multiplication and division problems. For example, in Lesson 21, Session 1, students use arrays and area models to determine the area of rectangles. The task prompts students to represent a real-world scenario involving tile patterns, where they must find the total area by creating an array and connecting it to the multiplication expression. The lesson guides students to analyze the information provided, choose an appropriate strategy (e.g., repeated addition or multiplication), solve the problem using a visual model, and justify their solution using mathematical language, such as rows, columns, and square units. This task aligns with TEKS process standards by developing problem-solving skills, modeling with mathematics, and encouraging the use of multiple representations to communicate reasoning.
