Mental first

56+ 29 or

+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
“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 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!
