Kristine.pngKristine Lloyd
Math Teacher


Kristine graduated from Stony Brook University where she received a B.S. degree in Physics with a minor in Anthropology. As part of the Women in Science & Engineering (WISE) Program at the university, she came to realize how important it is that young women are encouraged to succeed in math and science courses. This has led to a desire to work with students in STEM fields, especially math, at the late middle / early high school level.

Prior to working as a Math teacher at Thrive Public Schools, Kristine worked with 9th-12th graders as an Inclusion Specialist at High Tech High International. During this time she saw how providing time for students to work in groups and communicate their understanding of new concepts as well as progress at their own pace from their current math level helped students build their math skills. Bringing these lessons into Thrive’s blended learning environment, Kristine looks forward to helping all students see themselves as mathematicians over the course of the coming school year.  When not convincing students that math is fun, Kristine can be found enjoying time outdoors with her husband and son, wandering the streets/trails of San Diego with her camera, or sitting in the shade with her nose in a book.
