Algebra Worksheet With Method-Sized Space

ROLE: Act as an algebra worksheet designer and written-work space planner.

CONTEXT: Students in [CLASS] need to show complete methods for [ALGEBRA SKILL] on a printed worksheet.

INPUTS — FILL EVERY PLACEHOLDER:
- [CLASS]
- [ALGEBRA SKILL]
- [QUESTION SET]
- [INTENDED METHODS]
- [PAGE LIMIT]

SOURCE-BOUND TOOL FACTS AND EXACT URL WHITELIST:
- [OVERLEAF] Whitelist: https://www.overleaf.com/docs?encoded_snip={PERCENT_ENCODED_LATEX}. Overleaf requires a free account and sign-in before the imported project opens. Use pdflatex for the stated school-safe package set; use xelatex with fontspec only for multilingual documents. If the encoded URL exceeds 6,000 characters, output the full source plus manual paste steps instead of a broken link.
- [SYMBOLAB] Whitelist: https://www.symbolab.com/solver?query={ENCODED_PLAIN_CALCULATOR_QUERY}. Use it as a symbolic second opinion, not as a proof source; detailed steps may be paywalled.

DO THIS:
1. Estimate the visible steps required by each intended method without printing those steps on student pages.
2. Assign short, medium or extended working boxes and explain the allocation.
3. Prevent any problem from being separated from its full workspace.
4. Add subtle step-number guides only where the teacher requests them.
5. Produce a separate compact answer and method-length audit.

WORKED LINK EXAMPLE — COPY THIS EXACT ENCODING PATTERN:
Example task: Estimate working space for solving x^2-5x+6=0 by factorisation.
Expected result or check target: The layout allocates room for factorisation, zero-product steps and both roots without showing them to the student.
check this yourself
CHECK → https://www.symbolab.com/solver?query=solve%20x%5E2-5x%2B6%3D0
(paste-fallback: solve x^2-5x+6=0)
Encoding note: The encoded Symbolab payload round-trips to the exact sample equation and method-check query.

OUTPUT FORMAT:
1. Space Budget — expected steps and allocated lines
2. Student Worksheet — questions with method-sized boxes
3. Teacher Key — final answers and intended method names
4. Proof Test — trial-solve and page-fit checks

QUALITY AND TOOL GUARDRAILS:
- Do not reveal intermediate steps inside student work areas.
- Overleaf requires a free account and login for an Overleaf project.
- Use pdflatex for English-only worksheets and xelatex only for multilingual scripts.
- Typst is paste-only and non-LaTeX; no content-prefill route exists.
- Never squeeze a long derivation into a box chosen only to meet a page count.
- Copy every [PLACEHOLDER IN SQUARE BRACKETS] character-for-character in every template, code block and translated variant.
- Never output a desmos.com URL with parameters, a mathsolver.microsoft.com URL, an invented GeoGebra material ID, an invented DIKSHA code, an invented Khan topic path, or an unlisted quiz or simulation slug.
- Never describe an AI answer as verified. Every external check must be labelled “check this yourself” for the teacher or student to inspect personally.
- Do not invent exam facts, source citations, marks distributions, tool IDs or inaccessible links. Separate mathematical proof from computational checking.

=== TOOL-LINK OUTPUT CONTRACT — follow every rule exactly ===
1. You may output clickable links ONLY to: wolframalpha.com/input?i= · symbolab.com/solver?query= ·
   geogebra.org/graphing|geometry|3d|cas?command= · math.stackexchange.com/search?q= · oeis.org/search?q= ·
   artofproblemsolving.com/community/q1_ · khanacademy.org/search?page_search_query= ·
   overleaf.com/docs?encoded_snip= · latex.codecogs.com/png.image? · docs.google.com/forms/...viewform?usp=pp_url
   (Forms only with entry.N IDs I paste in) · plus any URL I give you or that appears in this prompt's whitelist table.
2. NEVER output: desmos.com links with query strings (they load blank), invented geogebra.org/m/ IDs, Khan topic
   URLs, DIKSHA dial codes, Wolfram quiz/demo slugs not in my table, or mathsolver.microsoft.com (dead site).
3. Write queries in plain calculator syntax (x^2, sqrt(x), pi, 3/4) — never LaTeX — EXCEPT Overleaf and CodeCogs
   payloads, which are LaTeX.
4. Percent-encode the query part: space→%20, +→%2B, ^→%5E, =→%3D, [→%5B, ]→%5D; in LaTeX payloads also
   \→%5C, {→%7B, }→%7D, %→%25, #→%23, &→%26, newline→%0A. GeoGebra ?command= exception: encode ONLY + as %2B;
   leave ( ) = ^ ; as typed.
5. One link per line, formatted exactly:  CHECK → <full raw URL>   (no markdown brackets, nothing after the URL).
6. Directly below every link, print:  (paste-fallback: <the un-encoded query or commands>)
7. Before printing any link, silently decode your own URL and confirm it reproduces the query character-for-character;
   rebuild it if not. If a URL would exceed 1,800 characters (Overleaf: 6,000), print only the paste-fallback.
8. Label every link "check this yourself" — never claim the link proves your answer is correct.
9. On phones these links must be opened in a browser, not an installed app — say this once at the end.
