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.

Verdict
The clearest difference is in-app purchases: ことわざ 勉強 at none against Think Why's 1. ことわざ 勉強 also leads on iOS requirement (13.0 vs 17.0). Think Why's advantage is ads (none vs shown) and update cadence (fortnightly vs every 4 months). On price and device support there is nothing between them.
