Adler's next project, a series of math books, drew on his experience as a math teacher. In that same year, a question from his then-three-year-old nephew inspired Adler to write his first story, A Little at a Time, subsequently published by Random House in 1976.

For the next nine years, he worked as a mathematics teacher for the New York City Board of Education, while taking classes towards a master's degree in marketing, a degree he was awarded by New York University in 1971. He graduated from Queens College in 1968 with a bachelor's degree in economics and education.

He was born in New York City, New York in 1947. David Abraham Adler is an American children's author.
