Can-do goal

You can hear, read and type ア・イ・ウ・エ・オ without answer choices.

カタカナ基礎：ア行

Click each character, listen, and imitate the sound. Then cover the romaji and retrieve it from memory.

Pronunciation focus

The sounds match hiragana exactly; only the shapes change. Compare ア／あ, イ／い and ウ／う. Compare standard print with careful handwriting; decorative font details are not new strokes.

Form and handwriting

• ア: three strokes; the final diagonal sweeps down left.
• イ: two separate diagonal strokes.
• ウ: three strokes; retain the short top mark.
• エ: three strokes; keep the middle vertical centred.
• オ: three strokes; the last stroke sweeps left.

Write each character slowly three times, then once from memory. Compare structure and stroke direction rather than decorative font thickness.

Mixed retrieval

The practice screen mixes roughly 70% current targets with 30% characters from mastered earlier groups. Practise both directions: character to sound and sound to character.

Mastery task

Complete recognition, listening and active recall practice. Each mode requires at least five attempts and 80% accuracy. Review the group again tomorrow before treating it as stable knowledge.
