Summary: This story is about a family on a road trip. In order to
keep the peace and make it to their destination without going insane the
O'Malley parents come up with a clever way of keeping their 3 kids entertained.
They create a tally mark game that keeps the kids busy and helps time pass
by faster. The O'Malley kids count up all the different color cars
and t-shirts they see. First Eric wins, then Bridget wins, but what about
little Nell. Surprise ending makes this a lively introduction to the
useful skills of tallying.
Rating: ***** I highly recommend this book for its great
introduction to Tally Marks. I think any child would enjoy listening and
visually looking at this story while learning this useful mathematical concept.
The story provides a real-life mathematical situation that students can relate
to.
Classroom Ideas: This book could be used with several mathematical topics that
include addition, subtraction and graphing/chart making. Students could use
observation in order to create different charts in class; different color
shirts, different hair color etc. Can even be used for learning about the
neighborhood and school by taking walking trips in order to create a chart that
represents something in school or area using tally marks.

This is a great book that children can relate to. Who hasn't taken a long road family trip and played the game that Tally and her family play along the way. This book is good for teaching a lesson on tallies and graphs.
