Fractions, decimals and percentagesWhat students need to learn:N10 work interchangeably with terminating decimals and their correspondingfractions (such as 3.5 and 72or 0.375 or 38); change recurring decimalsinto their corresponding fractions and vice versaN11 identify and work with fractions in ratio problemsN12 interpret fractions and percentages as operatorsMeasures and accuracyWhat students need to learn:N13 use standard units of mass, length, time, money and other measures(including standard compound measures) using decimal quantities whereappropriateN14 estimate answers; check calculations using approximation and estimation,including answers obtained using technologyN15 round numbers and measures to an appropriate degree of accuracy(e.
g. to a specified number of decimal places or significant figures); useinequality notation to specify simple error intervals due to truncation orroundingN16 apply and interpret limits of accuracy, including upper and lower bounds2. AlgebraNotation, vocabulary and manipulationWhat students need to learn:A1 use and interpret algebraic manipulation, including:• ab in place of a × b• 3y in place of y + y + y and 3 × y• a2 in place of a × a, a3 in place of a × a × a, a2b in place of a × a × b• ab in place of a ÷ b? coefficients written as fractions rather than as decimals? bracketsA2 substitute numerical values into formulae and expressions, includingscientific formulaeA3 understand and use the concepts and vocabulary of expressions, equations,formulae, identities, inequalities, terms and factors
