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”

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

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
