Sonia Kovalevsky Math Day is a fun-filled day of mathematics with hands-on workshops and talks for middle and high school female
students and their teachers, both women and men.
Originally started and funded by the Association for Women in Mathematics, the purpose of the day is to
encourage young women to continue their study of mathematics and to assist the
teachers of female mathematics students.
Free and Fun! Continental Breakfast and Lunch will be provided.

The Number Games: Survival of the Brainiacs
What do paying your friend, filling your water bottle, and stopping a super villain have in common?
Number theory! Many of the developments in modern mathematics came from games and puzzles of ancient times.
In this workshop we will discover this exciting branch of mathematics
by playing some real-life games. The topics we will cover are finding
an algorithm to calculate the greatest common divisor of two numbers,
modular arithmetic, and the Chinese Remainder Theorem.

The Fold-Cut Theorem
If you fold a piece of paper into quarters, you can cut a diamond out
of the middle with just one cut. What other shapes can you make? How
many cuts do they take? In this workshop, we will use folding to
minimize the amount of cuts you need to cut out a shape. Starting
with diamonds, triangles and squares, we will figure out what shapes
you can cut out with only one cut.

Tilings, Counting, and Symmetry
Imagine sitting in front of a chess board with a pile of dominoes.
How many ways could you arrange the dominoes on the board so that
every square was covered and no domino was hanging off the board?
What if we changed the shape of our chess board, or replaced dominoes
with a different shape? Given a board and a set of tiles, can we tell
when such a covering is possible? In this workshop, we’ll explore a
variety of puzzles like this, called tiling problems.
