Summary:
-->
Summary: Two friends play a guessing game and
discover a rewarding experience.
They enter a contest and win two free tickets to an All-Star Game all because of their estimating skills. They both used different strategies to guess how many people
are riding their bus, the cost of a bunch of toys, and how many jelly beans
fill a jar.
Rating: ***** I highly recommend this book as it stresses the importance of estimation. The story provides a connection to real-life mathematical experiences.
Classroom
Ideas: This book can
be used with several mathematical topics such as, addition, multiplication, and
estimation. Students can discuss real life occurrences such as :ordering pizza
to feed a number of people, how many tasks they can complete before going to
basketball practice or music lessons. Students could also come up with their
own idea of estimating problems.
