🎯 Tone Marks
A Vietnamese spelling game for first graders: a big word appears without its tone mark, six tone marks wait around it, and whichever one you tap flies onto the glowing vowel so the word transforms and is read aloud. Three ways to play: look at a picture and pick the tone that makes the real word, choose between the hoi and nga marks inside familiar phrases — the number one spelling mix-up — and tap the exact letter a mark should land on in words with two or three vowels. A wrong pick just wobbles, then pictures and a friendly voice show the difference, and five right answers in a row earn a star.
Tap a tone mark and watch it fly onto the glowing vowel: the word transforms and is read aloud right away. In Match the picture, pick the tone that fits the picture — a wrong pick makes a real but different word, and both words appear side by side with their pictures so you can hear the difference. In Hoi or nga, listen to the phrase and choose the correct spelling. In Where it lands, tap the exact letter the mark should sit on; a wrong letter shows the misspelling for a moment, then the right letter glows so you can try again. Tap the picture or the question card to hear it read again. Five in a row earns a star.
