The letters of a word have been jumbled up. Use the clue and tap the letters to rebuild it before the timer runs out. Ten words per round; faster solves score more, and a hint will cost you a few points.
Unscrambling forces a child to think about how words are actually built: common beginnings, endings and letter patterns. That letter-pattern instinct is exactly what good spellers rely on, and the definition clue sneaks in vocabulary practice at the same time.
