Play 'wipe out' to show the value of zero (as a place holder)

children types a number (eg. i type 462) in the calulator and asks
their partner to get rid of the 6...  and i have to return to zero in
the tens place. the children learn to take 60 away rather than six
(use as many digits as you wish).
