Year 6 Block A – Counting, partitioning and calculating
The focuses of mathematics learning within this block are:
 Addition and subtraction
 Mental calculations
 Efficient written methods: whole numbers and decimals
 Ordering, partitioning and rounding decimals to 3 places: +ve and ve integers
 Solving multistep word problems involving numbers, money or measures
 Explaining reasoning and conclusions, orally and on paper, using words, diagrams, symbols
 Multiplication and division
 Mental methods: TU × U, TU ÷ U and special cases
 Written methods: TU × TU, HTU × TU, HTU ÷ U, multiplying and dividing decimals by onedigit integer
The objectives for the block are listed in the table – the right hand column indicates how the objectives might be addressed in the units
Objectives 
Unit 1 
Unit 2 
Unit 3 
Explain reasoning and conclusions, using words, symbols or diagrams as appropriate




Solve multistep problems, and problems involving fractions, decimals and percentages; choose and use appropriate calculation strategies at each stage, including calculator use




Find the difference between a positive and a negative integer, or two negative integers, in context




Use decimal notation for tenths, hundredths and thousandths; partition, round and order decimals with up to three places, and position them on the number line




Use knowledge of place value and multiplication facts to 10 × 10 to derive related multiplication and division facts involving decimals (e.g. 0.8 × 7, 4.8 ÷ 6) 



Calculate mentally with integers and decimals: U.t ± U.t, TU × U, TU ÷ U, U.t × U, U.t ÷ U




Use efficient written methods to add and subtract integers and decimals, to multiply and divide integers and decimals by a onedigit integer, and to multiply twodigit and threedigit integers by a twodigit integer 



Use a calculator to solve problems involving multistep calculations




Use approximations, inverse operations and tests of divisibility to estimate and check results
