Year 9 ExamsThis booklet contains a sample Year 9 course outline as well as exams and practice exams for Year 9 and each of Terms 1, 2, 3 and 4. Problem solving, reasoning and communicating mathematical ideas are covered across all the strands of Number and Algebra, Measurement and Geometry, Statistics and Probability.

Encrypted MessagesThis is a PowerPoint designed for a oneoff lesson on encryption. It features 3 encrypted messages. The first is a verse from Lewis Carroll's "The Hunting of the Snark", the second is an encrypted message that has 3 parts  the message itself, a hidden number inside the verse both of which then point to a planet in the solar system. The last is a 3 x 3 (9 letter) square where all the letters stand for a number. In each of the cases clues are given for students to decode the messages. Teachers should read the PowerPoint first as all the answers are contained in subsequent slides.

Miscellaneous WorksheetsThis resource was sent to us by Barry Bellamy, a retired NZ teacher. There are sheets on Angles, Area, Algebra  collecting like terms, Circle Geometry, Decimal arithmetic, Factorising, Fraction Arithmetic, Percentages, Solving Equations, Statistics (mean, median, mode, range), Substitution, Solving Quadratics, Standard Form, Transformations (enlargement, reflection, rotation).
