Steve began his teaching career in 1968. From 197376, he attended UCLA fulltime and earned a Ph.D. in educational psychology, specializing in learning and instruction. He then returned to the classroom in Santa Monica, California, and taught middle school mathematics there until he retired in 2007. Janis began her teaching career in 1972, teaching 6th grade in an elementary school. After a year, however, she became a middle school math teacher in Santa Monica, then five years later a high school math teacher at Santa Monica High School. Steve and Janis published Mathimagination in 1973. This book introduced the use of selfcorrecting puzzles to provide practice for topics across the middle school math curriculum. Marcy Mathworks published a new edition of this book in 2003. Mathimagination was followed in the 1970's and 1980's with the three "Pizzazz" series of books: Middle School Math with Pizzazz, PreAlgebra with Pizzazz, and Algebra with Pizzazz.

In 2002, Steve and Janis published Punchline Bridge to Algebra. A second edition was published in 2009. This is a comprehensive set of puzzles for virtually all topics in today's prealgebra and beginning algebra programs. While the puzzles are mostly for individual students, there are also 10 puzzles for partners to work on together. Steve and Janis most recently published Punchline Algebra containing nearly 300 puzzles in two binders. Puzzles are provided for nearly every topic in today's Algebra 1 textbooks, with an emphasis on problem solving and on modeling realworld situations with equations, tables, and graphs. In 2011 Punchline Algebra became available as an interactive DVD disc. Steve and Janis have four grown children and live in Los Angeles. We hope you'll have an opportunity to try our books.
