###### Governor’s Square 15, Plaza Building

Math Circles are outreach programs for K12 teachers and students, often led by university-based mathematicians, which focus on providing authentic mathematical experiences – where participants enjoy and engage with mathematics as a lively discipline of inquiry, conjecturing, and problem-solving. Presenters will share mathematical problems and activities that can lead to hours of exploration by the curious.

**Friday, August 3**

10:00 am – 11:00 am: **Outreach Activities in Exhibit Hall: NAMC and SIGMAA-MCST booths**

###### Plaza Exhibit Hall, Plaza Building

1:30 pm – 2:50 pm: **Meeting the Challenge of Introducing Senior High School Students to Contemporary Mathematics**

###### Tower Court D, Tower Building

Consider the challenge mentioned in the title, why meet it and how? Our suggestion consists of periodically interweaving Mathematics-News-Snapshots (MNSs). We’ll examine a sample MNS against the rationale and the guidelines for MNS authors. Results from interweaving 21 different MNSs in Israel will be followed by a call for collaboration in (i) Developing new MNSs; (ii) Implementing existing MNSs empirically.

*A laptop is recommended for this workshop.*

Organizers:

**Nitsa B. Movshovitz-Hadar** and **Boaz Silberman**, *Technion*

Sponsor: The SIGMAA on Teaching Advanced High School Mathematics (SIGMAA TAHSM)

2:00 pm – 3:00 pm: **Outreach Activities in Exhibit Hall: NAMC and SIGMAA-MCST booths**

###### Plaza Exhibit Hall, Plaza Building

Activities: Origami, Frogs & Toads, Uncut Spaghetti, and Yarn Problems

3:10 pm – 4:30 pm: **Mathematical Puzzle Programs: Outreach and Recruitment with Puzzles**

###### Tower Court D, Tower Building

MaPP designs mathematical puzzlehunts for use in university outreach programs. Participating middle/high school students work in teams to solve fun mathematical puzzles based on contemporary mathematics research, many of which decode to locations around the host campus hiding more puzzles. Workshop participants will experience a mini-puzzlehunt for themselves and learn how to partner their institution with MaPP.

**Braxton Carrigan**, *Southern Connecticut State University*

**Steven Clontz**, *University of South Alabama*

**Saturday, August 4**

###### Plaza Exhibit Hall, Plaza Building

Activities: Origami, Frogs & Toads, Uncut Spaghetti, and Yarn Problems

10:00 am – 11:30 am: **Math Teachers’ Circle Demonstration**

###### Majestic Ballroom, Tower Building

A Math Teachers’ Circle is a professional development experience that brings mathematics professionals in direct contact with teachers. Circles foster passion and excitement for deep mathematics and give teachers a chance to connect with like-minded colleagues. This demonstration session offers the opportunity for conference attendees to observe and then discuss a Math Teachers’ Circle experience designed for local teachers. While the teachers are engaged in a mathematical investigation, mathematicians will have a discussion focused on appreciating and better understanding the organic and creative process of learning that circles offer, and on the logistics and dynamics of running an effective circle.

Organizers:

**Laura Janssen and Tom Clark**, *Dordt College*

1:30 pm – 2:20 pm: **Special Interactive Presentation for High School Students, Parents, and Teachers: **FREAKY FIXED POINTS

###### Majestic Ballroom, Tower Building

If you open up a map of the US while standing in the US, might there be a point on the paper sitting precisely at the location it represents? If you stir your (mathematically ideal) cup of coffee in the morning, does every point of liquid change location? If you crumple a piece of paper, does every point on it move?

Let’s play games with triangles to discover the freaky existence of fixed points!

Leader:** James Tanton**, *Mathematical Association of America*

Organizer:** Elgin Johnston**, *Iowa State University*

Sponsor: MAA Council on Outreach

2:30 pm – 4:00 pm: **MATH Rumble**

###### Majestic Ballroom, Tower Building

The Math Rumble involves teachers in a Mathematical Creativity Contest including mathematical and pedagogical questions. The intention of the Math Rumble demonstration at Math Fest is to share a fun mathematical contest format with those who lead Math Teachers’ Circles and similar activities.

Organizers:

**Ed Keppelmann**, *University of Nevada Reno*

**Phil Yasskin**, *Texas A&M University*

**Paul Zeitz**, *University of San Francisco*
