VầnTots
First steps in Vietnamese reading. Join a sound and a rhyme (bờ + a → ba), hear the six tones on one word (ma, mà, má, mả, mã, mạ) with a line showing how the voice moves, and build cá, gà or nhà one piece at a time. Spoken aloud in Vietnamese, big buttons, no score, no account. Ages 3-5.

Meet the cast
VầnTots' friends each do one thing with a Vietnamese word. Tí joins an opening sound to a rhyme. Mây draws each tone as a line across the sky, so you can see the voice go up or down. Sóc says every piece out loud, the way it is spelled in class. Bà Tư (the mentor) asks which word the pieces make.
