As this activity is for groups to work on and there are all sorts of possible outcomes, we haven't received many solutions.

However we had one very honest email from Aaron, who is from St.Helen's C of E Primary School:

First of all, the cards are dealt out randomly. Next without communicating, I concentrated on one person to get a complete set of cards by making sure they have all their numbers, fractions, decimals and pictures on them (e.g. $\frac{1}{2}$ and $0.5$).
Then I focussed on another and so on, then it made it easier to get the game finished, even though I struggled at the end to complete the game.
We found it hard to communicate, which was annoying because I wanted to complete the game quickly.
We found it easier to complete the game as we played more games!

Thank you Aaron and maybe when people read your message they may be encouraged to have a go themselves.
