Core (from Y9 teaching programme)
• Simplify or transform algebraic expressions by taking out single term common factors
• Use formulae from mathematics and other subjects; substitute numbers into expressions and formulae; derive a formula and, in simple cases, change its subject
• Add simple algebraic fractions |
Extension (from Y9 objectives for able pupils)
• Square a linear expression, expand the product of two linear expressions of the form x ± n and simplify the corresponding quadratic expression; establish identities such as
a 2 – b 2 = ( a + b )( a – b ).
Solve linear inequalities in one variable, and represent the solution set on a number line; begin to solve inequalities in two variables. |
