Geometry

Math is one of the foundational subjects in school that many students either hate or love. Here at TEEN DAY, teachers like Amanda Gray are pushing boundaries and encouraging students to see the subject in a new, refreshing light. One that isn’t so scary.

In her class, students are learning proofs and puzzle-solving. They’re doing parallel line proofs, congruent triangles, properties of triangles, and coordinate geometry. While there is still a good amount of calculator usage in geometry, it can be a big shift for students because it’s no longer about getting an answer, but rather knowing and explaining how that answer is true.

“She’s a good teacher— she explains things well and is very helpful with classwork and also makes it fun.” – Eloise L.

Classes are structured so that students get a mix of lecture, group work, class discussion, individual practice, and sharing. The mix of formats leads to various conversations of approaches to a problem or proof. Students can see things from multiple perspectives and can benefit from hearing how other people approach or see the same problem. Students are sharpening their individual critical thinking skills as well as building their confidence when asked to share aloud.

Additionally, students are applying what they’re learning in the classroom to real-world things. Over winter break, the students were asked to complete a “construction art project,” a collection of geometric shapes that were turned into artwork. Geometry doesn’t have to solely be about theorems and proofs, and instead can be used for various, fun designs. (See picture to the left and more pictures below.)

“…Amanda always makes math fun to learn. As someone who isn’t super math oriented, I’ve found that throughout algebra and geometry, Amanda has made the learning process quite a lot better than other experiences I’ve had.” – Addi F-W

Amanda Gray really enjoys math and science and works at Tompkins Cortland Community College (TC3) as a tutor in those subjects. In her free time, she works with TEEN DAY to provide excellent instruction on a wide range of subjects within the math and science fields. She wants to share her love of math with her students and help them to see the joy in the subject.

Overall, students are thriving in this collaborative setting and enjoying what they’re learning. Amanda’s instruction goes beyond that of the traditional classroom, with students sitting quietly in their seats, memorizing steps. But rather, her teaching style engages the students critically in the various stages of a problem, creating a unique and welcoming environment.

“It’s a classroom where students aren’t just doing geometry, they’re talking it through, questioning it, and starting to think like real mathematicians.” – Amanda Gray

Geometry is a part of a three-year rotation for lower-level math. First, Algebra I is offered, then Geometry, and finally Algebra II (which has a dual enrollment option). In 2026-2027, Algebra II will be offered, and the year after that, the cycle will reset, starting with Algebra I.

TEEN DAY Ithaca is in the process of hiring teaching staff for 2026-2027, and we’d love to connect with YOU!

There is often no demand for specific credentialing. Classes are/have been taught by professors, graduate students, undergraduate students, professionals, and enthusiasts of all stripes. We strive to find people who are, yes, comfortable in a room full of teens and confident in offering instruction on a subject. However, what we look for most of all are people who are passionate about what they’re doing. Whether it’s Algebra or Art, we’re after people who are willing to share their excitement about a topic with our participants. Most of our courses are offered 1 day/week on Tuesdays or Thursdays. Contact admin@teendayithaca.org for more info or to apply.

LOWER-LEVEL SCIENCE INSTRUCTOR:

Most of our educational areas at TEEN DAY operate in a three-year rotation, allowing most participants to take most classes, regardless of when they enter the program. Our lower-level science rotation consists currently of Life Science and Physical Science, with Earth Science being an overlapping year between our upper-level science courses. (Though from a teaching perspective, Earth Science is included in our lower-level course rotation.)

The ideal candidate will move through this rotation each year, teaching the relevant coursework. There is ample support for lesson planning and some existing infrastructure for labs and course planning. There is a lot of room for creative interpretation and outside-the-box instruction in all areas. Instructor applications will also be accepted for next year’s Physical Science course without the intention of teaching for TEEN DAY for the full rotation.

ART INSTRUCTOR:

Art classes at TEEN DAY operate in two different ways. Some years, we offer “generalist courses” with a connective theme or project that brings a variety of artistic modalities together, allowing participants to sample various techniques and art supplies all while working toward a new understanding of a topic. Some years, we offer expert instruction in a single medium or method, providing an opportunity for participants to delve deeply into one specific component of art (e.g., an En Plein course or one in Watercolor).

Previous Art courses that have been offered include: Oil Painting I & II, Mixed Media Art, Botanical Illustration, Stained Glass, Art of Being (art inspired by individuals). When applying for this position, applicants should propose a focus of study informed by their own interests and abilities.

LOWER-LEVEL MATH INSTRUCTOR:

Most of our educational areas at TEEN DAY operate on a three-year rotation, allowing most participants to take most classes, regardless of when they enter the program. Our lower-level math rotation consists currently of Algebra, Geometry, and Algebra II (cross-listed with Tompkins Cortland Community College as MATH120).

The ideal candidate will move through this rotation each year, teaching the relevant coursework. There is ample support for lesson planning. There is a lot of room for creative interpretation and outside-the-box instruction in all areas. Instructor applications will also be accepted for next year’s Algebra II (Math120) course without the intention of teaching at TEEN DAY for the full rotation.

CHEMISTRY INSTRUCTOR:

Our Upper-Level Science rotation in 2026-2027 is Chemistry. In this class, students should be introduced to key chemical principles, including topics such as atoms, molecules, chemical reactions, bonding, gases, liquids, solids, solutions, equilibrium, acids and bases, and organic chemistry. There is ample support for lesson planning with syllabi, lab recommendations and instructions, and notes from previous instructors. Text used: Introductory Chemistry (4th edition) by Nivaldo J. Tro
