Bit's Garden

For grown-ups: what each chapter teaches写给大人：每一章教什么

How it works: 12 chapters with 10 levels each. Each level is a little harder than the one before. Tap a map picture to jump to any level.
1 · Instructions: Bit does exactly what it is told, one tap at a time. Let children water the grass on purpose and laugh at the result.
2 · Plan a path: the whole program is planned first, then run. Ask “Where will Bit stop?” before pressing Run.
3 · Bug hunt: each level starts with a broken program. The red card shows where it went wrong. Praise calm checking, one card at a time.
4 · Repeat (loops): a card limit makes the Repeat card necessary. Ask “What keeps happening again?”
5 · Buttons (events): each row waits for its button. When the button is pressed, Bit runs that row. Children make their own controls.
6 · If: after a good run, Bit tests the same program again with the puddles in new spots, until every spot has been tried. The program can't be changed between tests, so only a program that checks with If passes.
7 · Build a garden: children design their own level, then program it. Each level adds a challenge, like using the Jump card or only 5 cards. Gardens are saved in this browser.
8 · Show and tell: nine review puzzles mix everything from Part 1. In the last level, their garden from chapter 7 plays as a show and ends with a certificate. Invite family to watch and give “two stars and a wish”.
Part 2 · Real code (age 8+): chapter 9 turns each card into a real line of Python-style code, like right(). Chapter 10 is typing and fixing code. Chapter 11 adds for loops and indentation, with a line limit. Chapter 12 adds if, if not / else and def for making your own commands, used inside loops too. Error messages name the line and say how to fix it.

怎么玩：一共 12 章，每章 10 关，一关比一关难一点。点地图小图，可以跳到任何一关。
1 · 指令：比特一次只做一件事，完全照着做。可以让孩子故意在草地上浇水，看着结果一起笑。
2 · 规划路线：先把整段程序规划好，再运行。按“运行”之前问问：“比特会停在哪里？”
3 · 抓虫子：每一关都从一段有错误的程序开始。红色卡片标出出错的位置。表扬孩子冷静地一张一张检查。
4 · 重复（循环）：卡片数量有限，必须用“重复”卡片。问问：“什么一直在重复？”
5 · 按钮（事件）：每一行都在等自己的按钮。按下按钮，比特就做那一行的事。孩子在做自己的控制按钮。
6 · 如果：程序成功一次后，比特会把水坑换到别的位置，用同一个程序再测试，直到每个位置都试过。测试中间不能改程序，所以只有用“如果”检查的程序才能通过。
7 · 造花园：孩子自己设计关卡，再给它写程序。每一关都有一个挑战，比如要用上“跳”卡片，或者只能用 5 张卡片。花园会保存在这个浏览器里。
8 · 展示：九个复习关卡把第一部分学到的本领都用上。最后一关，孩子在第 7 章做的花园会像表演一样播放，最后颁发证书。请家人来看，并送上“两颗星和一个愿望”。
第二部分 · 真正的代码（8 岁以上）：第 9 章把每张卡片变成一行真正的 Python 风格代码，比如 right()。第 10 章练习打代码和改错。第 11 章学习 for 循环和缩进，并限制行数。第 12 章学习 if、if not / else，以及用 def 做自己的命令，还会在循环里用它们。出错时会指出是哪一行，并说明怎么改。
