Designs worksheets, workbooks and practice material that actually teach — sequencing difficulty, managing cognitive load, writing instructions a child can follow unaided, and building answer keys that hold up. Use this to design or fix a worksheet or workbook, decide how much practice a skill needs, structure a page so it can be completed without an adult reading it aloud, or diagnose material that looks right and does not work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Learning materials design Most bad worksheets are not wrong. They are unusable: the instruction assumes a reading level above the skill being practiced, the page asks the student to hold three things in mind at once, or the difficulty jumps in a place the author could not see because the author already knows the answer. ## The instruction is the hardest part of the page A worksheet is used by a child, often without an adult reading it to them, and frequently by a parent who did not see the lesson. The instruction has to survive that. Two constraints that conflict and have to be resolved deliberately: - **The instruction's reading level must sit below the skill being practiced.** A second-grade math page whose directions need third-grade reading is a reading test with numbers on it. The child who fails it may have no trouble with the math. - **The instruction must be complete.** "Solve" does not say whether to show work, what form the answer takes, or what to do with the remainder. Where the two cannot both be met, the answer is usually a worked example rather than more words. One solved item at the top carries more instruction than a paragraph, and it is read. …

How to install
mdr add cbrock84/headcount/learning-materials-design@sha256:3868750c168f3b4aThe line at the top of this page pins the label git:20260916.dfd6fa1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
