the children to draw up a 7 x 7 grid (good skills!) and number 1-49. They
put numbers in any box, no set order - they must make sure their layout
is different to other children. Tell them to put 1 somewhere, then 2,
then 3 ...etc so they don't lose track of the numbers! The teacher they
uses various operations to ask questions - children work out answer and
shade in the box. Winner is the first to get a line. Less able can team
up to build confidence - it goes quite quickly! When they have mastered
this, change the numbers - I have used negative numbers, 50-98, multiples
of 10, etc...it is quite easy to extend. It takes about 15 mins to do.
I first saw this done in a Stanmore school by a shy teacher named Ian
Tyler - cheers Ian!'
