The 4th Grade Reading Challenge is a free educational game for Android developed by Peekaboo Studios. This game aims to help fourth-grade students improve their reading skills by providing them with original stories written by award-winning authors and teachers. Each story is accompanied by a set of questions, and the game requires the students to answer them correctly to show they have understood the story.

The game is aligned with the fourth-grade curriculum standards and provides specifically appropriate content chosen for this grade level. The stories are written specifically for the app, and each passage and question set takes just 5-7 minutes to complete. The game allows students to study anywhere and learn at their own pace, making it a great tool for parents, teachers, or students themselves to increase their reading scores.
