National Doodle Day Competition in conjunction with Just Mustard
Thanks to everybody who took part in the competition! The closing date has now passed and the winner have been contacted.
This year, thanks to gift company Mustard, National Doodle Day is running a competition where you could be winning a fab, Do It Yourself “doodle” Calculator.
“The DIY Calculator by Mustard adds fun and charm to maths, while subtracting almost every part of a normal calculator. Doodle away and design your very own adding machine on its blank canvas. There’s a template indicating where the digits and symbols need to go, the rest is up to your imagination. So no matter your age or style, this calculator will suit you.”
All you need to do to get involved is guess (calculate) how much the celebrity doodle auction will have raised by 4pm (GMT) on National Doodle Day!
