Cambridge Lower Secondary Mathematics — Stage 7
The whole Stage 7 course in one page: all 30 units and the three section reviews, each with a summary, key terms, worked examples, the mistakes to avoid, and graded exercises with answers. Tick off what you finish, write your own notes, and your progress is kept in this browser.
How to use this guide
Pick a unit from the list on the left. Read the summary and the worked examples first, then work through the exercises — Warm-up to settle the method, Core for the standard questions, and Challenge for the ones that make you think. Every question has an answer you can reveal when you are ready.
Tick each question as you finish it and the unit turns green. Use the star to flag anything you want to come back to. Everything you tick and note is saved in this browser, so your progress is waiting for you the next time you open the guide on the same device.
Teaching from this page? Press ✎ Draw in the guide's toolbar to write over it with a graphics tablet, stylus or interactive screen — pressure-sensitive pen, highlighter and eraser, plus a blank board for working an example. Flip the pen over to rub out, and keep clicking with the mouse while you write.
The Cambridge syllabus is taught and examined in English, so the lessons and exercises below stay in English even when the rest of the site is switched to Khmer.
