孩子从 0 和 1 一路学到 Transformer：不插电的课、可以打印的学习单、能在网页上动手的在线实验室。Kids learn AI from 0s and 1s up to Transformers: unplugged lessons, printable worksheets and hands-on online labs.
0与1，开与关0 and 1, On and Off只能传“是”和“否”，怎么把一句话传过去？从比特、字节一直到一个会学习的神经元。If you can only send yes or no, how do you send a sentence? From bits and bytes all the way to a neuron that learns.可打印Printable
最后一枚硬币：倒着想就能赢The Last Coin: Think Backward to Win25 枚硬币，每次拿 1–3 枚，拿到最后一枚的赢。倒着想，就能找到必胜的方法。25 coins, take 1 to 3 at a time, and whoever takes the last coin wins. Think backward and you find a way to always win.可打印Printable
猜词游戏：AI 怎么读懂一句话Guess the Word: How AI Reads a Sentence猜下一个词，猜被挖掉的词，再圈出帮你猜到的词。这就是今天 AI 读句子的方法。Guess the next word, guess a hidden word, then circle the words that helped. That is how today’s AI reads a sentence.在线实验室Online lab可打印Printable
电脑怎么“看”一张图How Does a Computer “See” a Picture?电脑没有眼睛。一张图就是一格一格的数：按数字涂色，再设计自己的秘密图让家长猜。A computer has no eyes. A picture is just squares of numbers: paint by numbers, then design a secret picture for a parent to guess.可打印Printable
吃豆人的鬼怎么追你？How Do the Pac-Man Ghosts Chase You?红鬼紧追，粉鬼埋伏，橙鬼一会儿追一会儿跑。每只鬼只有一两条规则，却像有性格。Red chases, Pink ambushes, Orange comes and goes. Each ghost has only one or two rules, yet each seems to have a personality.可打印Printable
管道里有噪音：我知道你翻了哪一张A Noisy Pipe: I Know Which Card You Flipped翻一张卡，老师回头一眼就找出来。多加一行一列“校验位”，错误能被发现，还能改回来。Flip one card and the teacher finds it at a glance. One extra row and column of check bits can find a mistake and fix it.点子Idea
管道被偷听：在全班面前说悄悄话Someone Is Listening: Whisper in Front of the Class凯撒密码、数字母来破解，再用“混颜料”在全班面前约定一把只有两个人知道的钥匙。Caesar ciphers, cracking them by counting letters, and mixing paint to agree on a key in front of everyone.点子Idea
管道太慢：怎样用更少的 0 和 1The Pipe Is Too Slow: Fewer 0s and 1s常见的字母用短码，重复的像素只记“有几个”。预测得越准，就能压缩得越多。Short codes for common letters, and just “how many” for repeated pixels. The better you predict, the more you can squeeze.点子Idea
教电脑认东西：训练数据会“带偏”Teaching a Computer: When Training Data Misleads只给电脑看过黑猫，它会怎么认白猫？AI 学到的是数据里的规律，不一定是我们想教的。If a computer has only seen black cats, what will it make of a white cat? AI learns the patterns in its data, which may not be what we meant to teach.点子Idea
要不要合作？信任的游戏Cooperate or Not? The Trust Game把一颗糖投进“机器”，它会变成 3 颗送给对方。你投不投？如果要玩 10 轮呢？Put one candy in the machine and your partner gets 3. Do you put it in? What if you play 10 rounds?点子Idea
说清楚：给机器人下指令Say It Clearly: Instructions for a Robot教一个完全照字面意思做事的机器人做果酱三明治。机器只做你说的，不做你想的。Teach a robot that takes every word literally to make a jam sandwich. Machines do what you say, not what you mean.点子Idea
排队大挑战：怎样最快排好序The Line-Up Race: How to Sort Fast6 个人走过一张画在地上的“排序网络”，走到终点就排好了。很多比较可以同时进行。Six kids walk through a sorting network drawn on the ground and arrive in order. Many comparisons can happen at the same time.点子Idea
感知机：一个会学习的神经元The Perceptron: A Neuron That Learns给每个格子一个分数，答错了就改分数。从 3 × 3 到 20 × 20，Python 代码现场就能改。Every square gets points, and wrong answers change the points. From 3 × 3 to 20 × 20, with Python code you can edit live.在线实验室Online lab
多层神经网络Neural Networks with Layers一个神经元做不到的事，几个神经元先分工、再一个综合就能做到。下一步：多层网络怎么学。What one neuron can’t do, a few neurons can: split the job, then combine. Next: how a layered network learns.大纲Outline
