Fractions in Disguise

Fractions in Disguise: A Math Adventure (Charlesbridge Math Adventures) is a math picture book that uses humor and a bit of robbery to engage students in reviewing the concepts of greatest common factors, lowest common denominators, and reducing fractions.

The story begins with fraction collectors gathered for an auction of a 5/9 fraction. During the auction, the lights go out and as in any good mystery the object disappears leaving the need to seek it out. George Cornelius Factor, GCF starts out on the journey to recover the 5/9 and in the process demonstrates the how and why fractions are reduced by finding the greatest common factor.

I love books that attempt to use humor, art, and fun to teach math concepts. I think this one might be a better review or post introductory book. I'm not sure I'd start my lessons on GCF and LCD with this book as it explains around the topic rather than directly defining. I think once kids had been introduced to the topics this would be a great, fun reinforcement of those concepts.

It also could just be used as a picture book that introduces the idea in passing without being too concerned with how much a child absorbs. The choice is really in the hands of the parent or teacher. The last page in the book does give a more formal explanation of how to reduce fractions. I did think this book might inspire some fraction art projects.

Full House an Invitation to Fractions

Full House: An Invitation to Fractionsinvites young readers to see fractions in action in an age appropriate manner.

In an author statement Ms. Dodds states, "Fractions were always a bit difficult for me to understand." In this book, she sets out to demonstrate that even young children can start to see fractions as parts of wholes and recognize their number format. She takes the fear out of fractions by introducing them at a young age, helping parents and teachers to demonstrate there is no boogey man fraction monster. It is just another part of math in our environment.

The story she weaves to help teach fractions is about Miss Bloom who runs the Strawberry Inn with six rooms including her own. She is hopeful of filling the Inn and as each guest arrives the readers are shown the fraction of rooms that are now filled. When the final guest arrives, the reader is shown how 6/6 is equal to one whole because the whole Inn is full. A final fraction story emerges regarding Miss Bloom's cake when the guests get hungry in the middle of the night and only leave her 1/6 the of the cake for herself.

I think this is another great book for introducing math concepts early in an age appropriate manner. I do not expect children to grasp fractions after reading this or any other children's picture book. However, it does plant a seed. With additional exposure, children do start to build math concepts. Thus, fractions and other math topics are no longer great mysteries to be tackled in later years.
