Divide and Ride (Dividing): In order to ride the Dare-Devil roller coaster at the Carnival, there must be two kids in each seat. But what if you're part of a group of 11 best friends? Ten kids will fit in five seats, but what do you do about the one who's "left over"? Meanwhile, chairs on the Satellite Wheel seat three, which means two best friends will be left over. Every ride presents a problem. Can the kids figure out how to fill all the seats so that everybody gets to ride? Understanding the meaning of remainders in simple division problems is a precursor to solving more difficult division problems. Illustrated by George Ulrich.
