Wrightington Mossy Lea Primary The approach to teaching calculation methods

3
Do it your way! 25x19 5% of 86 248-99 103-98 ½ of 378 475 4.3 149 5 189

4
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”

5
2000 -102 This is most sensibly done by counting back

6
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

7
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

8
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

9
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

10
The easy way to divide!

11
72 ÷ 4 = 472 we know 10 x 440 32 we know 8 x 432 0 18

12
96 ÷ 6 = 966 we know 10 x 660 36 we know 6 x 636 0 16

15
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 – 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

18
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
