** Happy Frog Apps is a Mom's Choice award winner. Our apps are featured on FunEducationalApps.com, TeachersWithApps.com and more! ** 'Fact or Opinion' builds an important comprehension skill in a fun, game-like environment. All kids need to know how to interpret what they read -- it is a fact, or is it someone's opinion? This skill is especially important as they reach the age of accessing information from the internet. ***** 5 Stars - I like how this app teaches kids how to look for the clue words that can identify a fact or opinion. No other app I've used has done that. ***** 5 Stars - Lots of practice. My son loves the Reward Center. Even I did a few levels so I could earn some coins to play! 'Fact or Opinion' is targeted to children in Grades 2-5. Beginning readers in earlier grades can also benefit from the targeted skill development. The focus of 'Fact or Opinion' is teaching kids how to identify whether a statement is a fact or opinion. This vital skill is built incrementally. Early levels focus on thinking about how to prove and fact/opinion and also how to identify the clue words that are indicative of a fact or opinion. Later levels include timers to ensure fluency. The app includes more than 300 examples for extensive practice. Key Benefits: - Builds comprehension skills step-by-step until mastery. - Incremental learning. New levels are unlocked only when your child is ready. - Frustration-free learning. Your child will always be guided to the correct answer. - Fun and engaging Reward Center to increase motivation. - Easy parental review. Just check out the stars to see how your child is doing. - Content designed by professional teachers and researchers. - Advanced levels include timers to ensure fluency. Research shows fluency in the foundation skills is critical to reading comprehension. - Can be used independently (just hand it over: your child will know what to do!) or with a therapist/parent for reading intervention. - Provides extensive reporting for up to 10 students to suit the needs of parents, teachers and therapists.

Verdict

The call

The clearest difference is ads: Fact & Opinion Skill Builder at none against Planet Math's shown. Fact & Opinion Skill Builder also leads on rating (5.0 vs 4.8) and iOS requirement (12.2 vs 15.0). Planet Math's advantage is update cadence (every 2 weeks vs every 24 months) and ratings volume (10 vs 1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
