Support (from Y8 teaching programme) • Consolidate standard column procedures for addition and subtraction of integers and decimals with up to two places • Use standard column procedures for multiplication and division of integers and decimals, including by decimals such as 0.6 or 0.06; understand where to position the decimal point by considering equivalent calculations
Core (from Y9 teaching programme) • Extend knowledge of integer powers of 10; multiply and divide by any integer power of 10 • Use rounding to make estimates; round numbers to the nearest integer or to 1, 2 or 3 decimal places. • Use known facts to derive unknown facts • Use a calculator efficiently and appropriately to perform complex calculations with numbers of any size, knowing not to round during intermediate steps of a calculation; use the constant, pi and sign change keys, function keys for powers, roots and fractions, brackets and the memory. • Enter numbers and interpret the display in context (negative numbers, fractions, decimals, percentages, money, metric measures, time • Round to a given number of significant figures • Make and justify estimates and approximations of calculations • Know that a recurring decimal is an exact fraction • Extend mental methods of calculation, working with decimals, fractions, percentages, factors, powers and roots; solve word problems mentally. • Use standard column procedures to add and subtract integers and decimals of any size, including a mixture of large and small numbers with differing numbers of decimal places • Multiply and divide by decimals, dividing by transforming to division by an integer • Solve substantial problems by breaking them into simpler tasks, using a range of efficient techniques, methods and resources, including ICT ; use trial and improvement where a more efficient method is not obvious. • Check results using appropriate methods
Extension (from Y9 objectives for able pupils) • Enter numbers and interpret the display in context (standard form) • Estimate calculations by rounding numbers to one significant figure and multiplying or dividing mentally
