2021 Mathical Book Prize FAQ

There is no submission fee for the 2021 Mathical Book Prize.
Mathical Book Prize winners are limited to frontlist titles only (published in calendar year 2020).
Publishers may submit up to 3 frontlist titles (published in 2020).
  • A single frontlist title (published in 2020) will be awarded the Mathical Book Prize annually in each of five age categories.
  • Additional frontlist titles may be named as Honor Books across the same age categories.
  • Both fiction and nonfiction titles may be submitted.
  • Textbooks, workbooks, kits, and experiment-only books are not eligible.
Books must be intended for grades Pre-K through 12.
  • All books must originate with a children’s publishing company or division and must be published (not simply distributed) by a publisher incorporated in the U.S.
  • Spanish-language editions published in the U.S. simultaneously with English-language editions are eligible.
  • Books translated into English are eligible.
Publishers will be contacted to share materials (such as high-resolution cover images) if any submissions are selected as 2021 winning titles or honor books.
For additional information, please contact Kirsten Bohl, Mathical Book Prize coordinator, at mathical@msri.org.
