School Block Challenge is an annual quilt block competition and exhibit, sponsored byModa Fabrics, for children grades K-12 nationwide. 

Moda generously provides three challenge fabrics that must be included in every block entry. Students can put their math skills & creativity to work in creating a quilt square of their own design. 

Entries are judged in the following categories: K-4th grade, 5th–8th grade, 9th–12th grade. Cash prizes are awarded to the teacher/parent of the winning students for arts/quilt education. All entries are included in the exhibition at The National Quilt Museum.
