The course will conclude with participants learning how to design activities that can be distributed to students through Jupyter notebooks.
02 - Just Five Good Precalculus Labs
Leader: Dan Butler, The Lovett School
Let's spice up our precalculus curriculum with some amazing labs. We will use GeoGebra, the TI-84, hands-on materials and anything else we decide we need to explore some of the concepts of precalculus through great problems, like using “Astronomy” magazine to teach transformations of trigonometric function, using paper folding to show basic trigonometric identities in a meaningful way, and a new look at the classic box problem. We will also take some time to discuss what needs to be in a precalculus course as well as how to fit these spicy problems into an already full curriculum.
03 - Calculus Before Calculus: Deepening Students' Understanding of and Appreciation for Mathematics
Co-Leaders: Ron Lancaster and Gurpreet Sahmbi, University of Toronto
Takeaways from this course will include strategies so that all middle and high school students can be exposed to topics covered in calculus without actually knowing any formal calculus. Another takeaway will be strategies for using technology and manipulatives that students can use to explore the fundamental ideas of calculus. The purpose of this course is not necessarily to promote the idea that all students should eventually take calculus, but that early exposure to calculus can deepen students' understanding of math and make their learning of math more meaningful with a deeper appreciation.
04 - Making It Relevant: Algebra I/II (Skew The Script)
Leader: Niki Wells, Skew The Script
We need citizens who can use math to analyze complex issues. So instead of checking the real world at the door, let's invite real issues into our math classes. In this course, we will explore lessons on relevant topics (e.g., voter power, food deserts, electric cars, social media, sports) from the Skew The Script Algebra I/II curriculum. We'll discuss how to use these activities to boost learning, engagement, awareness and critical thinking, all in a non-partisan way. Finally, we will generate strategies for facilitating productive and balanced classroom conversations on such topics.
05 - Gerrymandering with Math
Leader: Diana Davis, Phillips Exeter Academy
Gerrymandering was an intractable problem for many years, but recently some states have been making progress – thanks to math! In this course, we'll learn how to use modern techniques (the ones that convinced SCOTUS) to detect and measure gerrymandering by solving problems and discussing our solutions. Math tools we'll learn include random walks, graph theory, and outlier analysis, plus all the necessary political background. Come learn the tools to increase fairness, and then teach your students to do the same. A great course for geometry teachers – apply geometry reasoning in a new way!
06 - Creating and Planning a Diversity, Equity and Inclusivity Unit
Leader: Thomas Hill, Brewster Academy
In this course we will help you search for your starting point for DEI lesson planning. We will be using Learning for Justice's DEI standards that will frame how we look at lesson construction and implementation. We will be looking at high school curricula for examples. One specific case will be exponential population growth and China's one-child policy. We will spend time in group discussions and collaborating to create lessons and unit ideas. You will leave this week having gone through how to build a Diversity, Equity and Inclusivity unit and having had time to work with peers to create your own.
07 - Using and Building Desmos Activities to Provoke Student Thinking
Leader: Chris Bolognese, Columbus Academy
Desmos is not only a graphing calculator, but an online platform to allow students to explore deep mathematics. This course will explore pre-built Desmos activities for middle and high school grades and allow participants a chance to build their own Desmos activity to use in their classroom. No experience is required with Desmos Activity Builder. Resources will also be provided for more advanced users that want to explore the computational layer.
08 - Nurturing the Seeds of Calculus in the Middle Grades
Co-Leaders: Laurie Cavey, Boise State University and Tatia Totorica, Boise State University and Boise School District
Using a range of problem-solving strategies, we will explore rates of change and limits, two fundamental ideas in the study of calculus. In particular, we will consider situations involving constant rates of change and how we can support student understanding of related functional representations. With respect to limits, we will consider the infamous 0.9 repeating question (is 0.9 repeating equal to 1?) and other ways middle school students encounter the infinite. Along the way, we’ll examine how these ideas were both intuitively and more formally addressed throughout the history of mathematics.
09 - Beginning Math Teacher Workshop
Leader: Jessica Schenkel, Porter-Gaud School
This course is designed for teachers in their first five years of teaching. Regardless of your background, this course will provide an opportunity to reflect on past experiences and leave you refreshed and full of ideas for the 2023-24 school year. Jessica will share her experiences, successes and failures as a teacher and department chair in public, day and boarding schools. We will review trends in math education, how to put relevant research to practice, classroom management techniques, curriculum design, and how to create a classroom that supports the development of a growth mindset.
10 - Early History of Mathematics
Leader: Jeff Ibbotson, Phillips Exeter Academy
This course features an introduction to some of the early history of mathematics. Counting systems and numerals, early quadratic equations, the Pythagorean theorem and the early history of algebra will all be addressed.

28 - Proportional Reasoning 101
Co-Leaders: Laurie Cavey, Boise State University and Tatia Totorica, Boise State University and Boise School District
Proportional reasoning has often been referred to as the cornerstone of advanced science and mathematics. We will explore what it means to be successful with proportional reasoning — yes, it is more than just correctly setting up a proportion and solving! By solving a range of problem types, we will learn that proportional reasoning, at its core, involves reasoning sensibly about multiplication and division. And, by considering samples of student work, we will learn about a range of productive ways students can reason about proportional situations without the use of a formal algorithm.
29 - Writing a Problem-Based Curriculum
Leader: Diana Davis, Phillips Exeter Academy
Students learn math by doing math – specifically, by solving problems. In this course, you'll work on transforming one of your courses into a problem-based curriculum. You will figure what you want to accomplish, determine the steps along the way, map out when you will do all these things, and write the problems. We will also learn to analyze Exeter's problem-based curriculum so that you can pull problems out of it for your own use. We'll work through each other's problems and give each other feedback. At the end of the week, you will be well on your way to writing your curriculum.
