A Computer science / AI course for Class 6 with 13 chapters. Each chapter contains detailed lessons, practice with answers, and assessment activities.
The Extender is a second book that sits beside your Class 6 Computational Thinking and Artificial Intelligence book. It does not teach new topics. Instead, it gives every chapter extra room to grow: more worked examples, puzzles that go one small step further, and more practice with answers.
Each chapter of the Extender follows the same plan. First comes a short note on what the Extender adds. Then come eight bonus sections, numbered E1.1, E1.2 and so on, each one picking up a topic from the main chapter and taking it a step further. Every bonus section ends with a Your Turn question. After the bonus sections you will find an Extender Challenge with two harder puzzles, Extender Practice with multiple choice, short answer and think-and-solve questions, and finally the Extender Answers.
Use the Extender after you finish a chapter in the main book, or dip into one bonus section at a time as extra practice. Try every question on your own before you look at the answer. Getting stuck for a little while is part of learning to think like a computer scientist.
