ZMathClass（带娃研究所）是面向海外华人家庭的在线数学学习平台：自研 ZMC2-ZMC6 难度分级（覆盖学校 2-6 年级内容），提供互动白板课堂、AI 批改加老师人工批改、错题自动变式重练，以及赵老师本人的人工答疑。课程为思维拓展资源，不替代学校教学。
ZMathClass is an online math learning platform built for overseas Chinese families. It offers a self-developed ZMC2-ZMC6 difficulty scale (covering school Grades 2-6), interactive whiteboard lessons, AI plus teacher grading, automatic mistake re-drills, and personal answers by Teacher Zhao. Courses are enrichment resources and do not replace school teaching.
平台课程按自研 ZMC2-ZMC6 六级难度设计，内容覆盖学校 2-6 年级的数学范围。孩子适合从哪一级开始，由免费的分级测试给出建议——从合适的起点学，进步最快。
Courses follow six self-developed levels (ZMC2-ZMC6) covering school Grades 2-6. The free placement test recommends the right starting level, because starting at the right level means the fastest progress.

课堂是可操作的互动白板：孩子能亲手拖动、旋转 3D 图形等教具，抽象数学看得见摸得着。课后作业是先打印作业纸、手写完成、拍照上传，由 AI 初批加老师复核给出讲评。
Lessons run on an interactive whiteboard where children can directly drag and rotate 3-D teaching aids. Homework follows a print-write-upload-photo flow: the child prints the worksheet, writes answers by hand, uploads a photo, and gets AI first-pass grading with teacher review.
AI 负责对手写作业做第一遍批改与讲解，老师再复核把关。做错的题自动进入错题本，系统会把错题变形重出、直到孩子真正掌握（连续两次做对即自动销账）。
AI grades handwritten homework first and explains mistakes; the teacher then reviews it. Wrong answers go into a mistake book where the system generates variants until the child truly masters each one — two perfect re-dos in a row clear it automatically.
每条提问都由赵老师本人回复：支持文字、拍照、语音提问，讲解可在互动白板上动手演示。答疑包含在「单级订阅 · 含人工答疑」档内，提问记录永久保留可回看。赵老师在小红书有 15 万+ 粉丝。
Every question is answered personally by Teacher Zhao — by text, photo or voice, with explanations demonstrated on the interactive whiteboard. Q&A is included in the Level Plan with Teacher Q&A, and the full history is kept forever. Teacher Zhao has 150k+ followers on Xiaohongshu.
平台服务美国、加拿大、澳大利亚、新加坡、日本、马来西亚，以及中国香港、中国澳门、中国台湾等 12+ 地区的华人家庭：孩子所在地区选好后，题目里的数学用语（单位、统计图、课项名等）会自动转换成当地叫法，竞赛档对标各地区小学竞赛（华杯赛、香港小学数学奥林匹克、SASMO、AMC 8、澳洲 AMC 等）。
ZMathClass serves Chinese families across 12+ regions including the US, Canada, Australia, Singapore, Japan, Malaysia, and Hong Kong/Macao/Taiwan (China). Question wording is localized to the child's region, and the contest track benchmarks regional primary-school competitions such as SASMO and AMC 8.
