Brief session Descriptions 
Exploding Dots October 19, 2013 Exploding Dots (developed by noted math educator James Tanton) is a fun way to explore basic arithmetic, number bases, polynomials, decimals, geometric series, Fibonacci numbers, and more! In the process, we'll learn a bit about how to think like a mathematician and how to pose interesting mathematical questions. We'll also see how basic classroom concepts can connect to some really deep mathematics (and vice versa). 
Geometric Transformations November 16, 2013 Geometric Transformations have gained increasing prominence in the math curriculum since the introduction of the Common Core State Standards. During the presentation, we will use manipulatives to explore transformations in the context of frieze and wallpaper patterns. Using this handson approach, participants will see how problem solving techniques can work with diverse populations of students. A special education teacher will be on hand to share her perspective. 
Puzzles! December 14, 2013 “Make sense of problems and persevere in solving them" is the very first standard of the new Common Core. In this month's session, we'll explore some different types of puzzles and the various problemsolving strategies that we can use to solve them. The puzzles that we'll be solving have been created by Palmer Mebane, the current U.S. Puzzle Champion and the 2011 World Puzzle Champion. 
Fun with Dice January 11, 2014 Dice: what would we do without them? (We wouldn't be able to play Yahtzee, that's for sure.) Fortunately, dice have been around for thousands of years. There are loads of problems involving dice that we can pose, covering many different topics from middleschool and highschool math: geometry, number theory, combinatorics, statistics, probability, and so on. We'll look at a few of these problems, and maybe even invent a new dice game of our own!

Geometric Dissections February 8, 2014 Given a certain figure, when is it possible to cut it into pieces, and then reassemble the pieces to form another figure? For example, when can you turn a triangle into a square? Get ready to slice and dice as we explore this question, and other questions regarding geometric dissections.

TwoPlayer Games and Random Walks March 8, 2014 We'll explore some classic twoplayer games, and learn some techniques for determining a strategy to win at them. We'll also apply these techniques to the problem of "random walks", and hopefully see some realworld applications. (Note: we didn't actually get to to the topic of random walks during the session, but don't worry, we're saving it for a session for the 201415 year.) 
Volumes May 3, 2014 Volumes of pyramids, prisms, and other polyhedra figure prominently in the new Common Core State Standards. Students must not only know the volume formulas, but be able to understand them and explain them. In this extremely handson session, we will look at computing volumes from a variety of angles — no pun intended!
