One really fun summer sport is surfing, where you stand on a long surfboard and try to ride it on waves. Now imagine sharing one surfboard with dozens of other people! 66 people in California squeezed onto a 42-foot-long surfboard and rode it for a whole 15 seconds, beating the world record for the most surfers on the biggest surfboard. We hope once everyone fell off that somebody remembered to grab the surfboard.

*Wee ones:* If you surf the 1st wave, then skip the 2nd, then ride the 3rd, then skip the 4th, what do you do on the 5th wave?

*Little kids:* The surfboard was 11 feet wide, maybe almost as wide as your room! Lie down head to toe with a grown-up, and guess whether the 2 of you could stretch across that board. If you lay across it, by how many feet would you fall short of stretching across? *Bonus:* Once the 1st surfer fell off, how many of the 66 surfers were still hanging on?

*Big kids:* If the surfers weighed 10,100 pounds and the board weighed 1,300 pounds, how much did that weigh all together? (*Hint if needed:* Start with the board weighing just 1,000 pounds.) *Bonus:* If your regular surfboard is only 1/6 as long as this monster 42-foot one, how long is your board?

Answers:*Wee ones:* You ride the 5th wave.

*Little kids:* See if your height in feet + a grown-up’s height add to 11. *Bonus:* 65 surfers.

*Big kids:* 11,400 pounds. *Bonus:* 7 feet long.
