Texas Assessments of Academic Readiness (STAAR)
TX.STAAR.8. STAAR Grade 8 Mathematics Assessment
Reporting Category 1: Numbers, Operations, and Quantitative Reasoning - The student will demonstrate an understanding of numbers, operations, and quantitative reasoning.
(8.2) Number, operation, and quantitative reasoning. The student selects and uses appropriate operations to solve problems and justify solutions. The student is expected to:
8.2 (D) Use multiplication by a given constant factor (including unit rate) to represent and solve problems involving proportional relationships including conversions between measurement systems. Supporting Standard (STAAR)
Reporting Category 4: Measurement - The student will demonstrate an understanding of the concepts and uses of measurement.
(8.9) Measurement. The student uses indirect measurement to solve problems. The student is expected to:
8.9 (B) Use proportional relationships in similar two-dimensional figures or similar three-dimensional figures to find missing measurements. Readiness Standard (STAAR)
Underlying Processes and Mathematical Tools: These skills will not be listed under a separate recording category. Instead, they will be incorporated into at least 75% of the test questions in reporting categories 1-5 and will be identified along with content standards.
(8.15) Underlying processes and mathematical tools. The student communicates about Grade 8 mathematics through informal and mathematical language, representations, and models. The student is expected to:
8.15 (A) Communicate mathematical ideas using language, efficient tools, appropriate units, and graphical, numerical, physical, or algebraic mathematical models. (STAAR)
