31 is an activity, in which you get 25 cards and you have to place the cards so that each row (vertically and horizontally) add up to 31 or you have to use the numbers in order, in any equation to get the answer of 31. There should be 5 cards per row. (5 times 5)

We were not able to complete the challenge in the given time although we were very close, not only due to shortage of time but also because we did not really plan beforehand.

A strategy I used during the activity, was to use a variety of mathematical symbols and methods.

The most frustrating thing was when one row worked, the other did not work and we had to replace the cards again.

I used my problem solving skills when I had to figure out what card would work for both rows.
