About Year 9 maths
In Year 9 maths, the topics are grouped into 6 strands: Number (1), Ratio, proportion and rates of change (2), Algebra (5), Geometry and measures (4), Probability (1), Statistics (1). First, choose a topic in the list, then open its page. Every topic has a lesson, a worksheet with a separate answer page, multiple choice questions, a quiz, a test and starters. Also, most pages have a PDF, so you can print them for homework or revision.
Finally, when a topic feels easy, move on to the next one, because each topic builds on the one before. Because every topic page links to the others, you can switch from learning to practising in one click. Meanwhile, the sidebar shows the other year groups, so you can go back or move ahead. In addition, the answers always sit on their own page; therefore you can try first and check later.
