Challenge Level
There were just a few responses to this task. First, this is from Dylan who is at G.P.S in Australia, and it was accompanied by a screen shot.
This is technically a mathematics memory game that you have to press any card and find the answer to the math question then find a matching answer until you got all the cards right.
Secondly this came from Luke at St Mary's Church of England Primary School in Woodbridge:
I chose one tile at a time. Then I selected another one to go with it. I always pick the same first tile until I get a match. Then I move to a different first tile and so on.
Thank you for these, others may feel encouraged to have a go now.
