These are the person's own words, as shared in the source.

I want to build a Gem that creates a daily series of 20-question maths worksheets for children in Year 2. Each worksheet is to tap into the power of interleaving. The odd-numbered questions will cover a specific Theme for that day (ie a new concept that children need practice with). The even-numbered questions will cover a mixture of concepts from a Pool (a selection of concepts that children have met before). This Pool of concepts should grow with each day as the previous day’s Theme is added to the Pool.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Set up a reusable assistant that makes a short daily math worksheet for my child, mixing new and review topics.

Questions to ask me first:
- What grade is your child in, and which topics have they already learned?
- How many questions per day, and on paper or screen?
- How will you print it (PDF, Word or LaTeX)?

Inputs (fill in or confirm):
- Grade: [GRADE]
- Topics learned so far: [LIST]
- New topics in order: [LIST]
- Questions per sheet: [NUMBER]
- Format: [PDF / WORD / LATEX]

Rules:
- Odd questions practice the day's new topic; even questions review earlier topics, one question per topic.
- Add each day's topic to the review pool for the next day.
- Fit the questions on one page, with answers on a separate page.
- Keep numbers and wording right for the grade.

Checkpoint: Make Day 1 and Day 2 and wait for my feedback before saving the instructions.

If you get stuck: If my instructions conflict, ask me which rule wins instead of guessing.

Verify before you finish: Check every answer on the answer page before you finish.

Output: A printable worksheet and answer page for the day.

Done when: I can ask for the next day's sheet and print it in under a minute.

Gemini

Outcome

Craig Barton, a math teacher and author, wanted Isaac, Barton's 6-year-old son in Year 2, to do pen-and-paper math instead of more screen time. Barton built a Gemini Gem with a detailed prompt for daily 20-question worksheets that interleave practice: odd questions cover the day's new theme, and even questions mix in earlier topics from a pool that grows each day. Barton listed 60 themes in order and asked for one-page LaTeX output with answers on a second page. The first results weren't quite right and took several rounds of back-and-forth, which Barton says were mostly from an unclear prompt. Once the Gem was saved, each worksheet took about 20 seconds. Barton says the worksheets aren't better than ones Barton could write, but they save time. Isaac's verdict was mixed.
