Grace, Eli and Adam were up early and playing a jumping game. Someone would draw a card and then the would do that many jumps, knee drops and bum drops – 3 jumps per card in the playing deck (sans jokers).

Afterwards Grace and Eli went off to figure out how many jumps they had done from the cards.

They got to the right number – 1092!

Later in the day while I was mopping the playroom I looked and this and started thinking about how to get to the answer without counting. 3 x each of the cards in a suite is the same as 3 x the sum of the cards in the suite. 4 x that (for each suite) and the answer should be there. So, how do you calculate the sum of consecutive answers? I see a maths lesson in the future…
