In fact, quite a bit can be done with a big dot. I gave my son and daughter some large dots and we had fun experimenting with what we could make out of them.
However, art is not my reason for giving a thumbs up to this book. I like its math side.
For toddlers there is counting. And for older children (I would say preschool age) there is an chart at the end of the book which shows dots and numbers from 1 to 5 on the first page and 6 to 10 on the next two pages (only 5 dots fit per page). Having the numbers and dots shown in this manner is a marvelous way to let little ones see the `ladder' shape of the number pyramid. And an opportunity to point out how moving up or down the stairs is equivalent to addition and subtraction.
We like this book. It has a cute concept that is appealing to young children. (Toddler to Preschool)
4 Stars for being of mathematical as well as artistic interest.
