Middle School Math Mistake Review Assistant

Problem

When a student uploads a photo of a wrong junior-high math problem, the hard part is usually not copying it into an error notebook. It is extracting the exam point, the key logical turn, and a reusable practice path. If the record only keeps the original question and answer, the student may still fail on the same reasoning break when the problem changes slightly.

Workflow

The skill turns an uploaded mistake photo into a Markdown review file named by topic. It aligns the analysis with the 2025-2026 senior-high entrance math syllabus, covering numbers and expressions, equations and inequalities, functions, geometry, and statistics/probability.

The main pipeline includes:

• Question restoration: rewrite the stem in Markdown and LaTeX, such as $\triangle ABC$, $\cong$, and $\sqrt{x}$.
• Exam point: name the core concept, e.g., maximum of quadratic functions, circle tangent properties, or similarity criteria.
• Key insight: identify the decisive reasoning step in one or two sentences.
• Solution restoration: present complete solution steps rather than only the final answer.
• Variants: generate two same-difficulty questions with folded explanations, changing data or context while preserving the tested logic.
• Geometry SVG: for plane geometry, coordinate systems, function graphs, or composite shapes, output an SVG diagram with viewBox="0 0 600 500", arrows, labeled points, and dashed auxiliary lines; pure algebra or statistics/probability items state that no SVG is needed.

Limits

The skill assumes the model can read the uploaded image and that the photo contains both the original question and the standard answer. It is scoped to junior-high math review, not high-school math, university math, elementary olympiad, or non-math subjects. Generated variants and geometry labels should still be checked against the syllabus before formal use.
