Wrightington Mossy Lea Primary The approach to teaching calculation methods

Do it your way! 25x19 5% of ½ of

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

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 we know 8 x

96 ÷ 6 = 966 we know 10 x we know 6 x
