This rubric is designed to assess student performance in Grade 10 Mathematics; specifically within the Geometry and Algebra II strands. It provides clear criteria for evaluating conceptual understanding; problem-solving skills; and procedural fluency. The rubric supports educators in delivering consistent and objective feedback while helping students identify areas for growth. In Geometry; students are assessed on their ability to analyze shapes; apply theorems; and use deductive reasoning to solve problems. Key skills include proving geometric relationships; working with transformations; and applying trigonometric ratios to real-world scenarios. Mastery is demonstrated through accurate calculations; logical justification; and the ability to visualize spatial relationships. In Algebra II; the rubric evaluates students’ proficiency in manipulating algebraic expressions; solving equations and inequalities; and analyzing functions. Emphasis is placed on understanding polynomial; rational; and exponential functions; as well as interpreting graphs and modeling real-life situations. Strong performance requires clear mathematical communication; correct use of notation; and the ability to apply multiple strategies to complex problems. The rubric encourages a growth mindset by distinguishing between emerging; developing; proficient; and advanced levels of achievement. It highlights the importance of precision; critical thinking; and perseverance in mathematical tasks. By aligning with curriculum standards; it ensures that assessments are meaningful and reflective of students’ readiness for advanced coursework. Teachers can use this tool to tailor instruction; while students gain insight into their progress and areas needing improvement. Ultimately; the rubric fosters a deeper engagement with mathematical concepts and prepares learners for future academic challenges.
