Can-do goal

You can hear, read and type ナ・ニ・ヌ・ネ・ノ without answer choices.

カタカナ基礎：ナ行

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

Pronunciation focus

Compare ヌ with ス and ネ. The internal crossing and final direction identify the character. Compare standard print with careful handwriting; decorative font details are not new strokes.

Form and handwriting

• ナ: two crossing strokes.
• ニ: two horizontal strokes.
• ヌ: two strokes; the final stroke crosses the curved first stroke.
• ネ: four strokes with a central crossing and finishing sweep.
• ノ: one clean diagonal stroke.

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.
