  2. Unit 2 Decisions and Loops in Python Programs that choose and repeat, now in Python, with the turtle you already know. Algorithms and programming  
  3. Unit 3 Algorithms: Searching and Sorting How do you find one name among a million, or put them in order? Some ways are far faster than others. Algorithms and programming  
  4. Unit 4 Functions: Building Blocks of Programs Big programs are built from small parts, each with a name and a job. Algorithms and programming

How to use this book

A complete course of our own, not a guide to another book: the units build on each other in order, from what the best school computing courses in the world teach at this age, with examples from Nepal. Read them in order, and try every program yourself. Inside you’ll find:

  • Worked examples: try them first; the answer stays hidden until you open it.
  • Try it questions and each unit’s questions at the end, with hints and answers to open when you’re ready.
  • Diagrams to play with: drag, slide and change things to see what happens.
  • Did you know? boxes with the stories and surprises behind the computers.
