At a glance

Design a Concrete-Pictorial-Abstract learning sequence for a mathematical concept using manipulatives.

  • Works in 3 steps: Concrete (Enactive) → Pictorial (Iconic) → Abstract (Symbolic)
  • Teaching maths through Singapore method
  • SKILL.md covers What This Skill Does, Evidence Foundation, Input Schema and Prompt, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Cpa Sequence Designer is an agent skill from GarethManning/education-agent-skills. Design a Concrete-Pictorial-Abstract learning sequence for a mathematical concept using manipulatives. Use when teaching maths through Singapore method or when students struggle with abstraction.

Its SKILL.md is about 5.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 165 evidence-grounded AI skills for teachers, school leaders and EdTech builders—pedagogy, learning science, curriculum, assessment and regeneration. Claude, Codex and Hermes.

When your agent uses it

  • Teaching maths through Singapore method
  • Students struggle with abstraction

Example prompts

  • “/cpa-sequence-designer”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Concrete (Enactive)
  2. Pictorial (Iconic)
  3. Abstract (Symbolic)

What it can do on your machine

Read from SKILL.md and the folder at commit 6bbbce4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cpa Sequence Designer loads about 5.5k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 2,061 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~5.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,061 words (~5,513 tokens).

“Designs a learning sequence that moves students from concrete manipulation (physical objects), through pictorial representation (diagrams, bar models, number lines), to abstract notation (symbols and numbers) — following the CPA approach central to the Singapore Mathematics Curriculum Framework. The approach…”
