This book is divided into two sections, the first being written by Gibson and the second by Beechink.
This paragraph sums up the first part of the book really well
The trick is to integrate basic math into everyday life before your child even realizes he or she is “learning” something. Look for ways to creatively bring math into the child’s activities—ways that are actually fun so that from the beginning he or she associates math with positive thoughts.I have to admit that I found the second part of this book repetitious after reading Building Strong Arithmetic Thinking by Dr. Ruth Beechick. Very similar thoughts in these two books. But this paragraph does a basic summation of the second half of the book
After plenty of visualizing and concrete understanding, children will have little trouble learning what we call the “math facts.” They will already know most of them in their heads; others they can figure out because they are close to the facts they know; and only a few are left to memorize by rote.A good book overall. :)
But even with those larger numbers, children understand what is happening because of the concrete understanding they have acquired.
