Module Check: Teaching by Sorting
Wow — you made it to the end of Teaching by Sorting! You have covered a lot of ground over these ten lessons. You learned what sorting is, what labels are, how datasets are built, how machines find patterns, how testing works, and how to fix mistakes. Before we celebrate, let's do a quick review together to make sure all those big ideas have really stuck.

Module Quiz
Which of these is a sorting rule?
A machine is shown a photo of a banana with the word 'fruit' written next to it. What is 'fruit'?
What should a dataset contain?
Why is a test set kept secret from the machine during training?
A sorting machine mislabels orange cats as dogs over and over. What is the BEST fix?
What is a two-group sort?
You now understand the foundations of machine learning classification — in kid-friendly language, but with real ideas. Labels, datasets, predictions, test sets, and the fix-it loop are concepts that real machine-learning engineers use every single day. You are thinking like a scientist!
Teach Someone Else
- Find a friend, sibling, or family member who has not done this module.
- Tell them what a label is, using your own words and a concrete example from real life.
- Explain why a machine needs labeled examples to learn how to sort.
- Describe one thing that can go wrong and how you would fix it.
- Ask them a quiz question of your own invention and explain the answer.
- Teaching someone else is one of the best ways to prove — to yourself — that you truly understand something.
