解决钱币问题Money problems
给大人For Grown-ups
每一课先看晨晨和宁宁的视频，再做约 10 分钟的练习。孩子拖动代币付钱；答错了会提示是 说一说、想一想、算一算、查一查 哪一步，再试一次。没有计时、分数或连胜，三天后学会了就得到一张贴纸。
Each Lesson is the Episode, then a 10-minute Practice. A wrong answer gets a hint naming one of the four steps (Say it, Think, Work it out, Check) and another try. No timers, points or streaks; one Sticker when a Lesson is mastered.
