Supernova Sentence Puzzles

In Supernova Sentence Puzzles, kids select words to finish sentences based on parts of speech and sentence structure. Supernova Sentence Puzzles covers noun forms, verb forms, adjective forms, pronoun forms, adverbs, prepositions, conjunctions,  homophones, homographs, and more.

When a word is selected, the sentence is read aloud, giving children a chance to hear what their choice sounds like in the sentence. This combination of auditory and visual feedback helps kids determine whether or not the sentence is correct.

At the end of each round, kids can put together a puzzle using pieces they collect during the game.
