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 3: Geometry and Spatial Reasoning - The student will demonstrate an understanding of geometry and spatial reasoning.
(8.6) Geometry and spatial reasoning. The student uses transformational geometry to develop spatial sense. The student is expected to:
8.6 (A) Generate similar figures using dilations including enlargements and reductions. Readiness 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)
