Bears On Wheels

 By Stan and Jan Berentsain

Not Berenstein, as everyone seemingly used to pronounce it.

This book is amazing!  It teaches basic math!  I wouldn't call it an amazing counting book.  There are better books for that.

 The bears' shirts are different colours and the different vehicles that they ride or drive have different numbers of wheels.  It has 2+2, 1+3, 1+4, 5+5 and a few others.  Nothing incredibly difficult.  It's just a nice visual representation of the concept of adding and is really appealing to preschoolers.

My daughter seems to understand addition and I sincerely believe that this book made a big impact on that development.
