We all had 20 cards and we add all the numbers 1 to 20 and the answer was 210.
We divide 210 by 6 and that came to 35. Then we made piles of cards that add to the same number and that number was 35.we made 6 piles with the cards but some people made 5 piles then they made 6.Lots of people done different numbers like 50 ,34, 45 then 35. One group got six piles.
