This is a free poster that you can print out and hang in your room as an inspiration for your students: Maryam Misrakhami is the first woman to win the Fields Medal, the highest honor bestowed on a young mathematician. It is given to between 2 - 4 mathematicians to honor their promising work and is given every 4 years. Please spread the word to keep your girls excited about mathematics.
There is a full activity I've posted that links language arts and mathematics: it contains a 5 paragraph article I wrote about Mizrakhami's background as a child growing up in Iran, and the facts behind the Fields Medal. It also has several quotes from Mizrakhami about what it takes to master mathematics.
