Now available in Scholastic Bookshelf editions, the Brainy Day Books have been developed by nationally acclaimed math educator and best-selling author Marilyn Burns. Using entertaining fictional stories, these books dispel the myth that math is dry, inaccessible, and unimaginative. At the end of each book, there's a special section that further outlines math concepts and provides questions to further engage children.

Author and math teacher Marilyn Burns is noted for her many books that instill an interest and enthusiasm for mathematics into her school-age readers. Her books use traditional and original literature to address mathematical concepts. In addition to her instructive children's books Marilyn is the author of many books for teachers. She has also written books for children about food, time, and Hanukkah. She says that her writing career began as a fluke when a friend asked her to write a book about math. This was the jumping off point for her literary career, during which she has written about a dozen books for children and the same number for teachers. She currently gives lectures and lessons in schools. Burns was born in 1941 and resides in Sausalito, CA.
