Wrightington Mossy Lea Primary The approach to teaching calculation methods

Do it your way! 25x19 5% of 86 248-99 103-98 ½ of 378 475 4.3 149 5 189

Mental first 56+ 29 or 56 +29 Children cease to “say” the numbers, seeing only digits in columns e.g. “6 add 9” instead of “56 add 29”

2000 -102 This is most sensibly done by counting back

25x8 or 25 x 8 Children relying on written procedures forget how much they can do mentally. 25x8 is double 25x4 which is double 25x2

The calculating repertoire “Brain paper”: Mental recall of number facts Mental methods of calculation Real paper Jottings to record mental calculations Informal written methods Standard written methods

The calculating continuum Mental Recall Mental Calculations with jottings Informal Methods Expanded Written Methods Standard Written Methods Calculator No longer in Sats tests from 2014

The calculating repertoire Children constantly move up and down the continuum Learning a new method of calculating does not mean other ways are no longer relevant Children should always be looking for calculations they can do wholly or partly mentally

The easy way to divide!

72 ÷ 4 = 472 we know 10 x 440 32 we know 8 x 432 0 18

96 ÷ 6 = 966 we know 10 x 660 36 we know 6 x 636 0 16

Primary Curriculum 2014 Summary of changes Primary Curriculum 2014 Summary of changes

What will happen in September 2014 Reception will remain learning from EYFS Y6 will remain on the current National Curriculum in preparation for the 2015 national Sats tests. Y1 – Y5 will start to work on the new national curriculum in all subjects. New Sats tests will come into force in 2016

Mathematics – KS1  No data handling required  Rounding to nearest 10 removed from KS1  Y1: Counting & writing numbers to 100  Y1: Write numbers words to 20  Y1: Number bonds to 20  Y2: Finding fractions of quantities  Y2: Adding two-digit numbers  Y2: Telling the time to nearest 5 minutes  Y2: Make comparisons using = symbols  Y2: Solve simple money problems using £/p Mathematics – KS1  No data handling required  Rounding to nearest 10 removed from KS1  Y1: Counting & writing numbers to 100  Y1: Write numbers words to 20  Y1: Number bonds to 20  Y2: Finding fractions of quantities  Y2: Adding two-digit numbers  Y2: Telling the time to nearest 5 minutes  Y2: Make comparisons using = symbols  Y2: Solve simple money problems using £/p

Mathematics – LKS2  No ratio required in LKS2  Written division moved to UKS2  No calculator skills included  Carroll / Venn diagrams no longer required  Y3: Formal written methods for + & —  Y3: Compare, order & + & — easy fractions  Y3: Vocabulary of angles & lines  Y3: Time including 24h clock & Roman numerals  Y4: Recognise equivalent fractions/decimals  Y4: Solve fractions & decimals problems  Y4: Perimeter/area of compound shapes  Y4: Know multiplication tables to 12 x 12 Mathematics – LKS2  No ratio required in LKS2  Written division moved to UKS2  No calculator skills included  Carroll / Venn diagrams no longer required  Y3: Formal written methods for + & —  Y3: Compare, order & + & — easy fractions  Y3: Vocabulary of angles & lines  Y3: Time including 24h clock & Roman numerals  Y4: Recognise equivalent fractions/decimals  Y4: Solve fractions & decimals problems  Y4: Perimeter/area of compound shapes  Y4: Know multiplication tables to 12 x 12

Mathematics – UKS2  No calculator skills included  No probability included  Data handling greatly reduced content  Y5: Use decimals to 3dp, including problems  Y5: Use standard multiplication & division methods  Y5: Add/subtract fractions with same denominator  Y5: Multiply fractions by whole numbers  Y6: Long division  Y6: Calculate decimal equivalent of fractions  Y6: Use formula for area & volume of shapes  Y6: Calculate area of triangles & parallelograms  Y6: Introductory algebra & equation-solving Mathematics – UKS2  No calculator skills included  No probability included  Data handling greatly reduced content  Y5: Use decimals to 3dp, including problems  Y5: Use standard multiplication & division methods  Y5: Add/subtract fractions with same denominator  Y5: Multiply fractions by whole numbers  Y6: Long division  Y6: Calculate decimal equivalent of fractions  Y6: Use formula for area & volume of shapes  Y6: Calculate area of triangles & parallelograms  Y6: Introductory algebra & equation-solving
