** Featured on FunEducationalApps.com & theAppyLadies.com ** Inference Clues helps build strong reading comprehension skills in a fun, game-like environment. As well as generating inferences, players identify the clue words that lead to an inference -- a vital comprehension skill and part of the Common Core standards. ***** 5 Stars! This is another great app from Happy Frog. I really like how your apps target a specific skill. ***** 5 Stars Just what my son needed. Thanks for your great apps. We are working our way through all of them! Inference Ace 2 is targeted to children in Grades 2-5 who can read the words (decode), but who need help with understanding what they read. Key Features: - Builds inference skills step-by-step until mastery. - Incremental learning. New levels are unlocked only when your child is ready. - Can be used independently (just hand it over, your child will know what to do) or with a therapist for reading intervention. - Guided learning for less frustration. Your child will always arrive at the correct answer. - Fun and engaging Reward Center to increase motivation. - Advanced levels include timers to ensure fluency. Research shows fluency in the foundation skills is critical to reading comprehension. - Detailed reporting for up to 10 students to meet the needs of teachers, therapists and parents. Inference Clues can be used at the same time as Inference Ace (our other inferencing app), or it can be used after Inference Ace has been completed. You can try this app by downloading the free version. The free version has 4 free levels for one player. You can purchase levels and players separately through in-app purchases.
