Singing is an important early literacy activity because it helps kids to hear the different syllables in words as they are sung. This app reinforces that lesson with a physical motion for each syllable as the notes for the song, "Twinkle, Twinkle Little Star" are played -- one note for each time the device is shaken. Players therefore control not only the tempo of the song, but also the rhythm. Want to hear the song syncopated? Want to hear it super fast or sleepy slow? You decide! The visuals for this game are charmingly quirky cut paper designs that have minimal reaction to the screen being tapped, keeping the focus on the shaking and the music. Although the game is available on both tablet and phone, young children will have an easier time shaking the smaller device.
