Recommended for a pre-activity to the pizza fractions lesson, Gator Pie is a five-star illustrated children's book about alligators attempting to fairly share a pie. It's out of print and costs about $25 on Amazon, but it's easy to find in public library systems.
A suggested pre-activity for the above lesson plan is reading Eating Fractions (1992) by Bruce McMillan. This easy-to-find book consists of beautiful full-color photos showing one freckle-faced child and one dark-skinned child preparing and eating an assortment of delicious yet rather healthful foods. Each dish is first pictured as a whole and then in halves, thirds, or fourths. This book costs as little as $.01 on Amazon.
This high quality free lesson plan was created at the University of North Carolina School of Education.

This lesson plan involves manipulatives, using a website, word processing and spreadsheet creation. Pre-activities centered around storybooks are suggested.
