Dd2 age 5 can not grasp the concept of counting money. She counts the number of coins but does not understand the concept of "how much" - that the number on each coin needs adding to the number on the others.
e.g to her 2p+1p+1p=3p (because there are 3 coins).
I've tried playing shops, playdough money-making, stacking counters, coin rubbing.
There has to be a way of "showing" this concept (dd is bright but has language difficulties).
A friend's dc age 9, poss AS, is still grappling with the same concept.
Any off-the-wall ideas much appreciated.
Pleeeese.
