This book focuses on the topic of functions. I felt as if this book gave way too much information. The information tried to tied back to everyday life but got lost. There was no plot, just information that ran on for pages, which made it difficult to follow along. The illustrations were very dull, but that is understandable since the book is dated from 1974.

A Game of Functions introduces the concept of "functions." Functions are the same in math as they are in everyday life. Hunger is a function because it depends on when you ate last. It then shifts over to how functions are used in math.

This one might be a bit more advanced because I had some trouble understand it myself. It tries to gives kids an idea of what a function is by using situations of picnics and games. The paragraphs feel like they go one forever and the images do not help much. It feels very dated as well. I'm not sure how effective this book would be when read by itself. ( )

People can do many functions in everyday life, such as putting stamps on mail. There are simple functions, as well as complicated ones. ( )
