Katy Perry has partnered with US office supply store Staples to 'celebrate and support' education and teachers through the Make Roar Happen initiative.

Staples has donated $1m to DonorsChoose.org, a charity that has helped fund over 450,000 classroom projects for teachers, and will sponsor the North American leg of Perry's Prismatic World Tour to help raise more funds. Perry said she wanted to 'remind my fans that a small gesture can make a large impact on the very basic materials classrooms need for teachers to help students reach their full potential'.
