Key Stage 3 - Algebra

Standard KS3.OA.1.1 - Solve variable equations with decimals and fractions.

Included Skills:

Algebra

• Pupils should be taught to:

- use and interpret algebraic notation, including:

• ab in place of a x b

• 3y in place of y + y + y and 3 x y

• aÂ² in place of a x a, aÂ³ in place of a x a x a; aÂ²b in place of a x a x b

• a/b in place of a Ã· b

• coefficients written as fractions rather than as decimals

• brackets

- substitute numerical values into formulae and expressions, including scientific formulae

- understand and use the concepts and vocabulary of expressions, equations, inequalities, terms and factors

- simplify and manipulate algebraic expressions to maintain equivalence by:

• collecting like terms

• multiplying a single term over a bracket

• taking out common factors

• expanding products of two or more binomials

- understand and use standard mathematical formulae; rearrange formulae to change the subject

- model situations or procedures by translating them into algebraic expressions or formulae and by using graphs

- use algebraic methods to solve linear equations in one variable (including all forms that require rearrangement)

- work with coordinates in all four quadrants

- recognise, sketch and produce graphs of linear and quadratic functions of one variable with appropriate scaling, using equations in x and y and the Cartesian plane

- interpret mathematical relationships both algebraically and graphically

- reduce a given linear equation in two variables to the standard form y = mx + c; calculate and interpret gradients and intercepts of graphs of such linear equations numerically, graphically and algebraically

- use linear and quadratic graphs to estimate values of y for given values of x and vice versa and to find approximate solutions of simultaneous linear equations

- find approximate solutions to contextual problems from given graphs of a variety of functions, including piece-wise linear, exponential and reciprocal graphs

- generate terms of a sequence from either a term-to-term or a position-to-term rule

- recognise arithmetic sequences and find the nth term

- recognise geometric sequences and appreciate other sequences that arise.
