Some kids can calculate correctly and still get stuck on word problems. Think Why helps them slow down, make sense of the story, and see how the quantities fit together. Lessons use movable diagrams, short prompts, and guided practice. Children learn to: • identify what the question is asking • pick out useful information • connect quantities before choosing an operation • explain what an intermediate result means • check the answer in the original story • try the same idea in a new situation Think Why is designed for understanding, not speed or endless worksheets. Content is organized into six stages, from elementary foundations to more challenging reasoning. Try it free: • 2 complete courses in each stage • 1 Thinking Method • 1 Reasoning Challenge • practice for the included courses A one-time Full Learning Path purchase unlocks all 115 courses, 345 guided levels, 14 Thinking Methods, 12 Reasoning Challenges, full practice, stage check-ins, and weekly challenges. No subscription. No account, ads, tracking, or chat-based AI. Learning progress stays on this device. Purchases and restoration are handled by Apple.

Verdict
The clearest difference is ads: Think Why at none against こくごのべんきょう's shown. こくごのべんきょう's advantage is update cadence (weekly vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
