Number and Number Systems
Number topics include work on the equivalence of fractions, decimals and percentages to compare proportion, the calculation of percentage increase and decrease and the use of ratio and direct proportion to solve problems.
Standard column procedures for multiplication and division of integers and decimals will be consolidated. Calculator work will include the use of function keys, powers roots and fractions and the use of brackets. All mental methods of calculation will be extended to include work on products of decimal numbers, squares, square roots, cubes and cube roots.
Students will be taught to simplify or transform linear expressions and to substitute integers into formulae. Graph work will include the use of ICT to plot and investigate linear functions.
Shape, Space and Measures
Geometric reasoning using the angle properties of triangles and quadrilaterals is an important part of the shape work covered this year. Construction work and transformations will include the enlargement of 2D shapes and the investigation of simple loci and we will continue to develop the use of formulae to calculate area and volume.
The interpretation of graphs and charts plays an important part of this work this year, with the calculation of probabilities of combined events.
Students will learn to identify the necessary information to solve problems encountered in mathematics and other subjects, communicating their solutions and using logical argument.
