Powers and IndicesPowers (also called exponents or indices) are a short way of writing multiplication of the same factor. A knowledge of powers, is essential for an understanding of most algebraic processes. In this video and PDF you will learn about powers and rules for manipulating them through a number of worked examples.

Simulations, Chance and DataA 60 page book with notes and handouts to guide through simulations showing that situations don’t always come out as expected. Can we predict male/female compositions in families? How many winning streaks can you expect when playing against a person of equal ability? How many packets of tea do you need to purchase in order to collect 6 jigsaw pieces? What floor will people get off from an elevator? Do lie detectors really work? What is the Monty Hall dilemma? Do we need to worry about radioactive decay? What are the chances of having the same birth date as another in a room? How fast can an infectious disease spread? Can we predict lambing rates on a farm? What are the chances of not getting on the plane on your next flight?

Year 10 Math HomeworkAs with the Year 9 math homework sheets this set contains 40 weeks of 4 pages for homework or general class use. The sheets constantly revisit topics with a lot of the work presented in practical and real life situations. Students may have never visited the Pantheon in Rome but that doesn't mean you can't enjoy some mathematical applications derived from this famous landmark, analyse data taken of Rooibus tea, a doctors appointment book or maths questions from the Prime Minister. When should you return to work after a hit on the head? mathematics around a garage, drawing and interpreting parabolas and expanding two sets of expressions in brackets. Everything you need for Year 10 maths is included in these sheets.

-
Simplify and SolveThis 82 page booklet contains work on simplifying expressions, exponents, solving simultaneous equations using algebra and graphs. The pages are ideal for Year 10 and Year 11 Algebra and specifically work for the "Apply Algebraic Procedures in Solving Problems" external examination.
-
Expand and FactoriseThis booklet contains 70 pages of worksheets (with answers) cover simple expanding and factorising through to harder work with quadratics. In most cases there are 5 parallel question papers that you can complete. It is an ideal Algebra resource for Year 10 students through to Year 11 especially those that want to sit the MCAT exam AS91027 Apply algebraic procedures in solving problems.
-
Year 11 Algebra SkillsThis resource can either be used to determine whether you have the algebra skills needed to proceed into a Year 12 mathematics course or it can also be used to study for AS91027 (the Level 1 MCAT - Maths Common Assessment Task). There are worked examples, practice questions, and practice assessments with all answers provided. Topics include indices, manipulating brackets, expanding and factorising, solving linear equations and other algebraic expressions. The booklet is 26 pages in length.

Years 9-11, Angle Geometry LessonThis PowerPoint covers angle definitions and properties for Year 9, 10 and 11. It includes angles on a straight line, in a triangle, interior and exterior angles of a polygon and parallel lines. The lesson should take approximately an hour from start to finish. All the answers are included in the PowerPoint and there should be time to discuss and explain each concept as you work through the slides. Ideal as a wrap up to an angles or geometry unit of work.
-
Encrypted MessagesThis is a PowerPoint designed for a one-off 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.
-
Quadratic PatternsThis 30 slide PowerPoint guides you through Linear Sequences and then shows you how to find the equation of a Quadratic Sequence of numbers

-
Year 13, Differentiating by First PrinciplesDifferentiation is about rates of change for example, the slope of a line is the rate of change of y with respect to x. To find the rate of change of a more general function, it is necessary to take a limit. This is done explicitly for a simple quadratic function.
-
Year 13, Areas by IntegrationIntegration can be used to calculate areas under a graph. In simple cases, the area is given by a single definite but in more complicated cases the correct answer is obtained by splitting the area into several parts and adding or subtracting the appropriate integrals.
-
Year 13, The Quotient RuleThe quotient rule is a special rule that may be used to differentiate the quotient of two functions.
-
Graphs and GridsEver needed graph or log paper with different sized grids, a ready made set of axes for drawing lines, parabolas, hyperbolas or trigonometry graphs or some isometric lines or grids for drawing shapes? This 56 page booklet is the one for you. You will also find expanding circle templates, hexagonal and octagonal grids, 3 x 3 boxes for magic squares, fraction strips, fraction circles and squares, thermometers, protractors that can be printed onto clear plastic, number lines for integer arithmetic and 15 cm rulers that can be printed onto card.

SilhouettesWhat will be the odds? What does it mean when you read that heart attacks kill 1 in 5 people or that 1 in 8 women will get breast cancer? What does it look like when taken in context to a population? If taking a particular medicine improves the odds by 20%, how many will now survive? There are 4 pages in this document which give 200, 500, 1000 and 10,000 people silhouettes. They can be used in statistics exercises or by consultants to help illustrate what it actually looks like when given the odds.
