** Happy Frog Apps is a Mom’s Choice Award Winner! Also featured on FunEducationalApps.com, TeachersWithApps.com, and more! ** The “Comprehension Builder” app builds skills in passage comprehension, working memory and answering multiple choice questions about a text. What parents say about our awesome apps: *** 5 stars! Brilliant! An app that understands how kids actually learn. Thank you. *** 5 stars! Every one of your apps that I’ve tried is great! When using “Comprehension Builder”, your learner will first read a passage. The learner must then hold the information in memory in order to answer a multiple choice question. To build sustained attention and working memory, early levels contain 2-sentence texts with limited word count. As comprehension is demonstrated and memory increases, the texts increase in length and difficulty. “Comprehension Builder” contains 200+ fiction and non-fiction texts on a variety of topics. This app is perfect for learners who: - when reading or listening, information seems to ‘go in one ear and out the other.’ - have trouble responding to questions about a text unless they can refer back to the text. - can understand each sentence, but don’t seem to put them together to make meaning from the text as a whole. Additional Features: - Incremental learning. New levels are unlocked only when your child demonstrates mastery. - Fun and engaging Reward Center to increase motivation. - Contains over 600 questions, with content designed by professional teachers and researchers.
