Leaf It to Me

Label the sections of two spinners with the digits 0-9. Decide which spinner will be spinner A and which will be spinner B. For one partner, spinner A gives digits in tens place and spinner B gives units digits. For the other partner, spinner A gives units digits and spinner B gives digits in tens place.

Each partner makes the "stem" portion of a stem-and-leaf plot by writing the digits 0-9 in a single column and drawing a vertical line to the right. Both partners then spin the spinners at the same time. Each partner records the resulting two-digit number on his or her stem-and-leaf plot. The first partner to write five leaves beside any stem wins the round. Play several rounds.
