GREAT app for PreK students and beginning readers. My son plays this along with Endless ABC at age 2.

How I Use It

First students pick a work from the selection. They then place the letters into the correct order to spell the word. A sentence is then flown in with the word missing. Several monsters run through the sentence and two more words get displaced. The student then drags the words into the sentence where appropriate. The process is engaging and the students are rewarded each time with a short video with the monsters acting out the sentence.
